A composition and article of manufacture comprising a crosslinked polymer and a method of crosslinking a polymer are disclosed. The crosslinked polymer includes a polysiloxane and at least one hydroxycinnamic acid crosslinker. The method includes obtaining a polysiloxane and at least one hydroxycinnamic acid crosslinker, and reacting the polysiloxane and the crosslinker to form a crosslinked polysiloxane.

Hydroxycinnamic acid-derived crosslinkers

A composition and article of manufacture comprising a crosslinked polymer and a method of crosslinking a polymer are disclosed. The crosslinked polymer includes a polysiloxane and at least two dimerizable hydroxycinnamic acid crosslinkers. The method includes obtaining a polysiloxane and at least two dimerizable hydroxycinnamic acid crosslinkers, reacting the polysiloxane and the crosslinkers to form a crosslinked polysiloxane, and dimerizing the at least two hydroxycinnamic acid crosslinkers.

A method and system of reversibly absorbing liquid penetrations into electronic devices having a body and circuitry is described. The method and system comprises providing an absorbent sponge membrane structure in sheet-like form. The structure contains a hydrogel-forming core integrated into a blown polymer foam. The method and system includes placing the absorbent structure within the electronic device such that the hydrogel-forming core and blown polymer foam at least partly covers the electronic circuitry to be protected. A method and system in accordance with the present invention has the further advantage that due to the inclusion of the crystals into the open cells of the sponge, that structure is much easier to manufacture into various templates by punching or stamping holes where the keys and other mechanical obstructions such as bosses and supports must be accommodated.
