제목 Effect of the Raspberry-like PMMA-Silica hybrid nanoparticles on the mechanical and thermal properties of PLA/Acrylic Elastomer blends
초록 In this study, PLA blends with an Acrylic elastomer as block copolymer (MMA-co-BA) and Raspberry-like PMMA-Silica hybrid nanoparticle at various compositions were prepared from the internal mixer. Hybrid nanoparticles were prepared using tetraethyl orthosilicate (TEOS) via sol-gel method in the presence of PVP-functionalized PMMA with a silica content of about 15 wt%. The flexibility of PLA increased about 150 % by adding the optimized amount, about 30 wt% of the acrylic elastomer. The addition of hybrid nanoparticles on the PLA/Acrylic elastomer blends showed increase tendency in the mechanical and thermal properties, and it was found that the silica having difficulty to be dispersed in polymer induced from the hydrogen bonding is well dispersed in PLA/ Acrylic elastomer blends. This could be attributed to not only the physical dispersion of raspberry-type PMMA-Silica, but better compatibility between PMMA and PLA, a carrier system in the blend.
