An adhesive strain sensing pod includes at least one strain sensor, electronics for electrically sensing at least one strain signal from the at least one strain sensor, and a sensor adhesive for adhering the strain sensor to a surface of a structural element. The pod may have a protective case for protecting the strain sensor and the electronics and for transferring at least part of a force, pressing the pod against the surface, to press the strain sensor against the surface. The sensor adhesive may be a liquid adhesive contained in a fragile pouch that ruptures when the pod is forced against the surface, or may be a thermally activated adhesive film that is activated to bond the strain sensor to the surface. A protective film may protect the sensor adhesive prior to installation of the pod and is removed prior to installation of the pod on the surface.

Polymeric films, which may be adhesive films, and display devices including such polymeric films, wherein a polymeric film includes: a first polymeric layer having two major surfaces, wherein the first polymeric layer includes a first polymeric matrix and particles. The first polymeric layer includes: a first polymeric matrix having a refractive index n.sub.1; and particles having a refractive index n.sub.2 uniformly dispersed within the first polymeric matrix; wherein the particles are present in an amount of less than 30 vol-%, based on the volume of the first polymeric layer, and have a particle size range of 400 nanometers (nm) to 3000 nm; and wherein n.sub.1 is different than n.sub.2.

A continuous method of manufacturing adhesives is provided. The method includes obtaining an actinic radiation-polymerizable adhesive precursor composition disposed on a major surface of an actinic radiation-transparent substrate and irradiating a first portion of the actinic radiation-polymerizable adhesive precursor composition through the actinic radiation-transparent substrate for a first irradiation dosage. The method further includes moving the actinic radiation-transparent substrate and irradiating a second portion of the actinic radiation-polymerizable adhesive precursor composition through the actinic radiation-transparent substrate for a second irradiation dosage. Optionally, the method also includes irradiating a third portion of the actinic radiation-polymerizable adhesive precursor composition through the actinic radiation-transparent substrate prior to moving the substrate. The first irradiation dosage and the third irradiation dosage are often not the same, thereby forming an integral adhesive having a variable thickness in an axis normal to the actinic radiation-transparent substrate.

The invention relates to a thermally activatable reactive adhesive film comprising a carrier film made of thermoplastic polyurethane, which is coated on at least one side with a latently reactive, thermally activatable adhesive compound.

A component comprising a first outer region (11), at least one intermediate region (13) and a second outer region (12). The outer regions (11, 12) have a higher density and/or a higher elastic modulus than the at least one intermediate region (13). A polymer composition (21) can, preferably, be injected into the component (1) such that a mechanical connection (41) is fixed or can be fixed in the polymer composition (21). A method, a kit and the use thereof are also disclosed.

Embodiments of the present invention are directed to a two-layer adhesive and methods of using the same to secure an electronic device to an organism. In a non-limiting embodiment of the invention, a surface of the organism is coated with a first adhesive layer (bottom layer). The first adhesive layer is cured and a surface of the cured first adhesive layer is coated with a second adhesive layer (top layer). An electronic device is positioned on the second adhesive layer prior to curing the second adhesive layer. The second adhesive layer is then cured, thereby embedding the electronic device within the second adhesive layer. The bottom layer and the top layer are selected such that the bottom layer releases upon exposure to a first solvent after a first duration and the top layer releases upon exposure to a second solvent after a second duration more than the first duration.

Problem: An object of the present invention is to provide a polyester film for a foldable display, the film having a hold angle in a bending direction of 155° or more and a maximum heat shrinkage at 150° C. of 1.5% or less (wherein the hold angle refers to an angle of a crease after fixing the film at room temperature for 72 hours in such a manner that a strain of 1.7% is applied to both surfaces of a bent portion of the film, and the bending direction refers to a direction that is orthogonal to a folding portion of a foldable display produced using the film.

A method for altering adhesion properties of a surface of a substrate by a coating, comprising the steps of: a) ionizing a plasma gas at low temperature and at atmospheric pressure, thereby creating a plasma with a plasma temperature of at most 50° C.; b) introducing a precursor into a plasma gas afterglow of the plasma; c) subjecting the surface of the substrate to the plasma including the precursor, thereby forming a coating onto the surface. The plasma gas is essentially completely comprised of inert gas. The coating alters the adhesion properties of the surface.
