Controlled synthesis and characterization of core-shell fluoro-silicone-containing fabric agent

The core-shell particles containing fluorine-silicon polymer was prepared by activators regenerated by electron transfer atom transfer radical polymerization(ARGET-ATRP)using SiO2-Br as initiator.The obtained polymer with well-controlled molecular weight and low polydispersity was used as water and oil repellent fabric finishing agent.Kinetics of the polymerization showed the polymerization was a living/controlled system.Characterization of FT-IR,1 H NMR,19 F NMR,XPS,TEM confirmed the core-shell structure of the polymer and the presence of F element.The formation of dual micro-nano structure between nano polymer and the surface of fabric enhanced the water and oil repellency of the cotton fabric.
