摘要: Cellulose nanocrystals (CNCs) are sustainable rigid rod-shaped nanoparticles that have potential as reinforcing agents in polymer nanocomposites. CNCs can also act Pickering stabilizers emulsions and foams due to their amphiphilic nature. In this work, were rendered surface active through adsorption with the biopolymer methyl cellulose (MC) produce MC-coated CNCs. used stabilize microsuspension polymerization of methacrylate. Monomer conversion, latex size, gel content studied. The resulted a double morphology where poly(methyl methacrylate) (PMMA) microparticles produced simultaneously. ratio micro- could be tuned based on CNC:MC ratio. Most attached offering hierarchically structured latexes, although approximately 2 wt % free suspension. Drying conditions control roughness dry la...
