Poly(Methyl methacrylate-Butyl acrylate) (MMA-BA)/Polythiourethane [PMBA-PTU] core-shell nanoparticles were synthesized by "New Click Reaction" based on a prepared poly(MMA-BA) copolymer nanoparticle using soap-free emulsion polymerization. "New Click Reaction" is defined as reaction between 1,1,2,2-perfluorodecanethiol (PFDT) and trimethylsilyl isocyanate (TMI), in which PFDT and TMI are subsequently catalyzed by triethylamine (TEA) to produce a polythiourethane network, forming core-shell nanoparticles. To demonstrate that trimethylsilyl groups of TMI can be used as surface coating agents, several were reacted with cellulose. From field-emission scanning electron microscopy (FE-SEM) and transmission electron microscopy (TEM), the resulting core-shell nanoparticles are in good sphrical shape and their shell is consisted of a compact PTU layer with water-oil repellent property. Finally, the roughness of PMBA-PTU films were analyzed by atomic force microscopy (AFM). In accordance to the thickness of PMBA-PTU films, the roughness of this films was found to vary.
