Li, Hao; Jilili, Yikelamu; Zhen, Weijun; Zhao, Ling published the artcile< Preparation, performance and structure-properties relationship of poly(lactic acid)/modified saponite nanocomposites based on thiol-ene click chemistry>, Category: alcohols-buliding-blocks, the main research area is structure property relationship polylactic acid modified saponite nanocomposite.
Saponite (SA)-mercaptopropyl polyhedral oligomeric silsesquioxane (POSS-SH) grafted poly (L-lactic acid) (SA-POSS-PLLA) was synthesized by thiol-ene click chem. SA-POSS-PLLA was characterized by Fourier transform IR spectroscopy and XPS. When 0.3 wt% SA-POSS-PLLA was used as a modifier in poly(lactic acid) (PLA), the impact strength and elongation at break of PLA/SA-POSS-PLLA nanocomposites were increased by 1.73 times and 4.25 times compared with pure PLA, resp. The differential scanning calorimeter anal. showed that the crystallinity of PLA/SA-POSS-PLLA nanocomposites was increased from 7.74% to 30.32%. The addition of SA-POSS-PLLA increased the crystallization rate of PLA and significantly reduced the grain size of PLA, which also was proved by polarization optical microscopy anal. Rheonaut technol. for simultaneous rheometry and FTIR demonstrated that the reason why the addition of SA-POSS-PLLA nanoparticles accelerated the crystallization rate of PLA was that SA-POSS-PLLA nanoparticles promoted the adjustment of C-O-C structure and -CH3 group in the main mol. chain of PLA.
