Biodegradable Poly(l-lactide)/Polyhedral Oligomeric Silsesquioxanes Nanocomposites: Enhanced Crystallization, Mechanical Properties, and Hydrolytic Degradation

Biodegradable poly(l-lactide) (PLLA)/polyhedral oligomeric silsesquioxanes (POSS) nanocomposites were prepared in this work via solution and coagulation method at various POSS loadings in order to get a better dispersion of POSS in the PLLA matrix. Scanning electron microscopy observation indicates that POSS were nicely dispersed in the PLLA matrix. The overall crystallization rates are faster in the PLLA/POSS nanocomposites than in neat PLLA...
