Surface Properties of Epoxy Resins Modified by Polyether-grafted Polysiloxanes
Abstract:
Polyether-g-polysiloxane copolymers were prepared through hydrosilylation and used as a modifier for epoxy resin. The results indicated that the static friction coefficient of the cured epoxy resin was effectively reduced by the incorporation of the copolymers, and the contact angle with water enhanced. The morphology and surface properties of the cured epoxy resin depended mainly on the structure and content of polyether chains in the graft copolymers, as well as the level of the copolymer. The surface composition of the cured epoxy resin was analyzed by XPS. It was suggested that remarkable enrichment of the polysiloxane chain on the surface of the cured epoxy resin was responsible for the improvement of the surface properties.
