Claim 16:
17. A method, comprising:
adding a printable precursor composition comprising (i) methacrylic acid or acrylic acid and (ii) a solution comprising polydimethylsiloxane, polydiphenylsiloxane, or a combination thereof; and tetraethyl orthosilicate, tetrapropyl orthosilicate, or a combination thereof to a digital light processing printer;
polymerizing the methacrylic acid or the acrylic acid using the digital light processing printer to provide an intermediate structure comprising a polymerized scaffold comprising polymetharylic acid or polyacrylic acid in physical association with the solution comprising the polydimethylsiloxane, the polydiphenylsiloxane, or both; and the tetraethyl orthosilicate, the tetrapropyl orthosilicate, or the combination thereof;
exposing the intermediate structure to a temperature ranging from ambient temperature to 100° C. to cure the polydimethylsiloxane, the polydiphenylsiloxane, or both; and the tetraethyl orthosilicate, the tetrapropyl orthosilicate, or both to provide a cured polysiloxane-polymerized scaffold hybrid structure comprising a polysiloxane having a polymer backbone that consists of oxygen-silicon bonds; and
removing the polymerized scaffold from the cured polysiloxane-polymerized scaffold hybrid structure by exposing the cured polysiloxane-polymerized scaffold hybrid structure to a washing solution.
