The slurry can be applied 406 to the top surface of the adhesive layer by any known method. In some embodiments, the slurry is applied 406 by one of spraying, ink jetting, doctor blade coating, dip coating, brushing, roll coating, spin coating, slot die coating, solution casting, flow coating, or calendering. In some embodiments, more than one intermediate hydrocarbon permeable layer is required, and the method further comprises repeating the applying 404 a top adhesive layer to a top surface of an intermediate hydrocarbon permeable layer and a bottom adhesive to a bottom surface of the intermediate hydrocarbon permeable layer, the applying 405 the bottom adhesive layer to the top slurry layer to sandwich the top slurry layer, and the applying 406 a slurry to the top adhesive layer to sandwich the intermediate hydrocarbon permeable layer and to create a new top slurry layer.

[0068] In some embodiments, the method further comprises applying 407 a second adhesive layer to a surface a cover layer, and the applying 408 of the second adhesive to the top slurry layer to sandwich the top slurry layer. In some embodiments, the second adhesive is applied 407 to the entire surface the cover layer. In some embodiments, the second adhesive is applied 407 to a portion of the surface the cover layer.

[0069] The method further comprises drying 409 the one or more slurries to create one or more dried slurry layers. The one or more slurries can be dried at ambient temperature and pressure. In some embodiments, heat is applied to the one or more slurries to decrease the time required to dry 409 the one or more slurries. The method further comprises affixing 410 the one or more dried slurry layers to the one or more adhesive layers. In some embodiments, the one or more adhesive layers are comprised on pressure-sensitive glue and are affixed 410 to the one or more dried slurry layers by applying pressure to the adhesive.

[0070] The present disclosure is not to be limited in terms of the particular embodiments described in this application, which are intended as illustrations of various aspects. Many modifications and variations can be made without departing from its spirit and scope, as will be apparent to those skilled in the art. Functionally equivalent methods and apparatuses within the scope of the disclosure, in addition to those enumerated herein, will be apparent to those skilled in the art from the foregoing descriptions. Such modifications and variations are intended to fall within the scope of the appended claims. The present disclosure is to be limited only by the terms of the appended claims, along with the full scope of equivalents to which such claims are entitled. It is to be understood that this disclosure is not limited to particular methods, reagents, compounds, compositions or biological systems, which can, of course, vary. It is also to be understood that the terminology used herein is for the purpose of describing particular embodiments only, and is not intended to be limiting.

[0071] With respect to the use of substantially any plural and/or singular terms herein, those having skill in the art can translate from the plural to the singular and/or from the singular to the plural as is appropriate to the context and/or application. The various singular/plural permutations may be expressly set forth herein for sake of clarity.

[0072] It will be understood by those within the art that, in general, terms used herein, and especially in the appended claims (for example, bodies of the appended claims) are generally intended as open terms (for example, the term including should be interpreted as including but not limited to, the term having should be interpreted as having at least, the term includes should be interpreted as includes but is not limited to, et cetera). While various compositions, methods, and devices are described in terms of comprising various components or steps (interpreted as meaning including, but not limited to), the compositions, methods, and devices can also consist essentially of or consist of the various components and steps, and such terminology should be interpreted as defining essentially closed-member groups. It will be further understood by those within the art that if a specific number of an introduced claim recitation is intended, such an intent will be explicitly recited in the claim, and in the absence of such recitation no such intent is present.

[0073] For example, as an aid to understanding, the following appended claims may contain usage of the introductory phrases at least one and one or more to introduce claim recitations. However, the use of such phrases should not be construed to imply that the introduction of a claim recitation by the indefinite articles a or an limits any particular claim containing such introduced claim recitation to embodiments containing only one such recitation, even when the same claim includes the introductory phrases one or more or at least one and indefinite articles such as a or an (for example, a and/or an should be interpreted to mean at least one or one or more); the same holds true for the use of definite articles used to introduce claim recitations.

[0074] In addition, even if a specific number of an introduced claim recitation is explicitly recited, those skilled in the art will recognize that such recitation should be interpreted to mean at least the recited number (for example, the bare recitation of two recitations, without other modifiers, means at least two recitations, or two or more recitations). Furthermore, in those instances where a convention analogous to at least one of A, B, and C, et cetera is used, in general such a construction is intended in the sense one having skill in the art would understand the convention (for example, a system having at least one of A, B, and C would include but not be limited to systems that have A alone, B alone, C alone, A and B together, A and C together, B and C together, and/or A, B, and C together, etcetera). In those instances where a convention analogous to at least one of A, B, or C, et cetera is used, in general such a construction is intended in the sense one having skill in the art would understand the convention (for example, a system having at least one of A, B, or C would include but not be limited to systems that have A alone, B alone, C alone, A and B together, A and C together, B and C together, and/or A, B, and C together, et cetera). It will be further understood by those within the art that virtually any disjunctive word and/or phrase presenting two or more alternative terms, whether in the description, claims, or drawings, should be understood to contemplate the possibilities of including one of the terms, either of the terms, or both terms. For example, the phrase A or B will be understood to include the possibilities of A or B or A and B.

[0075] In addition, where features or aspects of the disclosure are described in terms of Markush groups, those skilled in the art will recognize that the disclosure is also thereby described in terms of any individual member or subgroup of members of the Markush group.

[0076] As will be understood by one skilled in the art, for any and all purposes, such as in terms of providing a written description, all ranges disclosed herein also encompass any and all possible subranges and combinations of subranges thereof. Any listed range can be easily recognized as sufficiently describing and enabling the same range being broken down into at least equal halves, thirds, quarters, fifths, tenths, et cetera. As a non-limiting example, each range discussed herein can be readily broken down into a lower third, middle third and upper third, et cetera. As will also be understood by one skilled in the art all language such as up to, at least, and the like include the number recited and refer to ranges that can be subsequently broken down into subranges as discussed above. Finally, as will be understood by one skilled in the art, a range includes each individual member. Thus, for example, a group having 1-3 cells refers to groups having 1, 2, or 3 cells. Similarly, a group having 1-5 cells refers to groups having 1, 2, 3, 4, or 5 cells, and so forth.

[0077] Various of the above-disclosed and other features and functions, or alternatives thereof, may be combined into many other different systems or applications. Various presently unforeseen or unanticipated alternatives, modifications, variations or improvements therein may be subsequently made by those skilled in the art, each of which is also intended to be encompassed by the disclosed embodiments.
