| Abstract: | Graft copolymer latex polyisoprene-silk sericin(PL-g-SS) were synthesized by emulsion polymerization using two-component redox-initiation system(cumene hydroperoxide and tetraethylene pentamine).The structure and performance of PL-g-SS were confirmed by NMR,TEM and particle size analyzer.The results showed that SS fully grafted from the isoprene backbone,and the amphiphilic PL-g-SS nanoparticles showed clear core-shell structure,where the PL cores were coated with SS shells.Additionally,PL-g-SS nanoparticle... |
