A polymer matrix composite comprising a porous polymeric network; and a plurality of at least one of polar solvent soluble particles or polar solvent swellable particles distributed within the polymeric network structure; wherein the polymeric network structure is insoluble relative to the soluble particles, wherein the soluble particles are present in a range from 1 to 99 weight percent, based on the total weight of the at least one of soluble particles or swellable particles and the polymer (excluding any solvent); and wherein the polymer matrix composite has particles that at least one of (a) upon exposure to a polar fluid, release at least some component from the polymer matrix composite layer or (b) upon exposure to a polar fluid, absorb some of the polar fluid; and methods for making the same. The polymer matrix composites are useful, for example, in delivery devices comprising the polymer matrix composite, wherein the at least one of soluble particles or swellable particles comprise at least one of an active agent or a released agent.

A germ-repellent plastic contains an anti-biofouling compound, and a basic plastic. The anti-biofouling compound is optionally selected from the group of a polyol, a polyether polyol, a polyol derivative, and a combination thereof; or the anti-biofouling compound is selected from the group consisting of a polyether, a poly (ethylene glycol) ether, a polysorbate, and a combination thereof; or the anti-biofouling compound is selected from the group consisting of poly (ethylene glycol) sorbitan monolaurate, poly (ethylene glycol) sorbitan monooleate, poly (ethylene glycol) sorbitol hexaoleate, ceteareth, and a combination thereof. The basic plastic is not a blend of a low-density polyethylene polymer and an ethyl vinyl acetate copolymer, a blend of a polypropylene polymer and an ethyl vinyl acetate copolymer, a blend of polyolefin elastomer polymers and a polyvinyl chloride polymer. A method for manufacturing such a germ-repellent plastic and a germ-repellent plastic item are also described.

A double network hydrogel consists of a first network and a second network, where the first network is, or includes, a first polymer that is formed, at least in part, of CH.sub.2CH(OH) units, and the second network is, or includes, a second polymer that is formed, at least in part, of carboxyl (COOH)-containing units or salts thereof, sulfonyl (SO.sub.3H)-containing units or salts thereof, and at least one of hydroxyl (OH)-containing units or amino (NH.sub.2)-containing units, where the hydrogel may be used as a cartilage replacement.

A preparation method of a three-layer self-healing flexible strain sensor includes steps of: preparing an encapsulating layer composite, so as to obtain a concentrated solution; preparing a strain sensitive layer composite, so as to obtain a thick liquid; dropping the thick liquid on a glass substrate, and statically curing at a room temperature; dropping the concentrated solution on a cured film obtained in the S3, and statically curing at the room temperature; striping a cured filmed obtained in the S4 from the glass substrate, and drawing out two wires as electrodes; and dropping the concentrated solution on the other surface of the cured film obtained in the S3 with a same amount of S4, and statically curing at the room temperature for obtaining the three-layer self-healing flexible strain sensor. The three-layer self-healing structure strain sensor can be prepared without using a repair agent, but can achieve rapid self-repair.
