L-Lysine-Based Dendritic Gelator Modified PMMA Nanocomposite

Abstract

L-lysine-based dendritic gelator(G3-C12-G3) was successfully designed and synthesized using a divergent approach and it can self-assemble into nanofibers in MMA followed by gelation. After thermal polymerization of MMA gels, the self-assembly nanofibers modified PMMA nanocomposite can be obtained. SEM studies indicate the embedded supra molecular nanofibres joint each other and form a relative intact gel networkskeleton in PMMA matrix. Impact strength and DMTAmeasurementindicatethe existence of gel network skeleton make PMMA nanocomposite had higher impact strength and storage modulus than pure PMMA. UV-vis spectrophotometer studies indicate PMMA nano-composite retains high light transmittance.
