ELASTIC PARYLENE
Elastic Parylene films produced via chemical vapor deposition polymerization (CVDP) on a substrate are disclosed.
Plasma Assisted Parylene Deposition
A method for depositing parylene onto a substrate includes utilizing a vaporization chamber and a pyrolysis chamber to crack a dimer into a monomer gas, directly ionizing the monomer gas by passing the monomer gas through a plasma generation chamber comprising plasma prior to injection of the monomer gas into a deposition chamber, and polymerizing the ionized monomer in the deposition chamber to create a polymer and a protective coating on a substrate.
Three-dimensional porous structure of parylene
The present invention provides a 3D porous structure of parylene including a poly-p-xylylenes structure having a plurality of pores. The poly-p-xylylenes structure has a porosity. According to an embodiment of the present invention, the size of the porous structure is between 20 nm and 5 cm. According to an embodiment of the present invention, the porosity is between 55% and 85%. According to an embodiment of the present invention, the porous structure further includes a plurality of target molecules. According to an embodiment of the present invention, the pores of the poly-p-xylylenes structure include pore sizes of different sizes. The pore sizes are varying in a gradient. According to an embodiment of the present invention, the porous structure is formed integrally.
Composite coating and fabrication method thereof
The present disclosure provides a composite coating and a method for fabricating the composite coating. The composite coating comprises a polymer layer, a metal interlayer and an amorphous metal coating. The polymer layer is formed on a substrate and acts as a diffusion barrier layer, which is thick and dense enough to prevent the corrosive substances from penetrating into the substrate. The metal interlayer is formed between the polymer layer and the amorphous metal coating for improving the adhesion of the amorphous metal coating to the substrate.
Cryopreservation of cell-seeded substrates and related methods
Disclosed herein are methods and compositions for the identification of viability enhancing cell features and substrate features as they relate to post-cryopreservation survival of substrate seeded cells. Embodiments of the present invention further involve identification of cell features to manufacture a supernatant that is useful for cell culturing and treatment of various diseases.
SUBSTRATES FOR ELECTRONIC SKINS
A substrate for use in an electronic skin is disclosed herein. The substrate comprises a base polymer layer, and a first intermediate polymer layer attached to the base polymer layer by a first adhesive layer. The first intermediate polymer layer comprises a first intermediate polymer in which electron-rich groups are linked directly to one another or by optionally substituted C.sub.1-4 alkanediyl groups. A first conductive layer is attached to the first intermediate polymer layer by a second adhesive layer or by multiple second adhesive layers between which a second intermediate polymer layer or a second conductive layer is disposed.
