Surface modification of epoxy resin by amphiphilic fluoroorganosiloxane copolymers
- 40 Downloads
An amphiphilic fluoroorganosiloxane copolymer designed for a surface modification of epoxy resin by fluorine-containing fragments has been synthesized. The copolymer contains anchor units with terminal amino groups forming chemical bonds with the epoxy matrix. The composition of the surface layers as a function of the content of the copolymer modifier has being studied by the XPS method. The presence of anchor units affects the degree of segregation and the concentration profile of the fluorocontaining groups in depth.
