New Nanocomposites Study Findings Reported from Beijing University of Chemical Technology

摘要

"Isothermal and nonisothermal cold crystallization behaviors of biodegradable poly(L-lactide) (PLLA)/octavinyl-polyhedral oligomeric silsesquioxanes (ovi-POSS) nanocomposites at low ovi-POSS loadings were investigated in this work. For both neat PLLA and its nanocomposites, the overall isothermal cold crystallization rates increase with increasing crystallization temperature, moreover, the overall isothermal cold crystallization rates of PLLA increase With increasing the ovi-POSS loading in the nanocomposites relative to neat PLLA, indicative of the nucleating agent effect of ovi-POSS," scientists writing in the journal Industrial & Engineering Chemistry Research report.
