Composite material with self-healing properties and release of active ingredients, for biomedical applications

摘要

Self-healing composite material comprising: a) a polymer matrix; b) microcapsules or nanocapsules containing a polymerization agent, said microcapsules or nanocapsules are dispersed within said polymer matrix; c) an agent dispersed within said polymeric matrix and suitable for activating the polymerization or cross-linking of said polymerization agent, wherein said agent which is dispersed within the polymeric matrix is a catalyst or an initiator selected from diethylenetriamine, tetraethylenepentamine, 2 , 4,6-tris-dimethylaminomethylphenol, triethylene diamine, piperidine N, N-dimethyl, benzyldimethylamine, 2- dimethylaminomethylphenol and 2-dimethylaminoethanol, characterized in that the polymerization agent is an oligomer precursor of a thermostable resin selected from glycidyl phenol ethers, glycidylamines, bisphenol A diglycidyl ether, phenolformaldehyde novolac polyglycidyl ether, novolac o-cresol formaldehyde polyglycidyl ether, N, N, N ', N'-tetraglycidyl methylenedianiline, bisphenol A novolac, triglycidyl ether triglycidyl ether -aminophenol and 3,4-epoxycylhexylmethyl 3,4-epoxycyclohexane carboxylate, for use in application Dental
