英文摘要
In order to realize a tailor-made medical treatment considering region and degree of disease, mechanical and hydrolysis properties for poly(L-lactic acid)/ tri-calcium phosphate composites were investigated experimentally and analytically as a function of the content of tri-calcium phosphate. Mechanical behavior was predicted based upon modified micromechanics. Molecular weight distributions, as hydrolysis behavior, were analytically predicted considering self-catalytic effect of carboxyl group. Since it is confirmed that variations in mechanical behavior associated with hydrolysis is caused by degradation around interphase between tri-calcium phosphate/ poly(L-lactic acid), mechanical behavior was predicted considering interfacial debonding with hydrolysis. In addition, mechanical properties of the composites were improved with an interfacial treatments.
