摘要：

In order to reduce static friction coefficient (mu (s)), polyether-polydimethylsiloxane-polyether triblock copolymers (PER-PDMS-PER) were incorporated into epoxy resins as surface modifiers. It was found that longer PDMS segments in PER-PDMS-PER and higher modifier contents led to lower mu (s) of modified epoxy resins upon stainless steel. The mu (s) of silicone rubber- and PTFE-side surfaces were evidently lower than that of stainless steel-side surface. ESCA investigations indicated that a longer PDMS block in modifier resulted in a flatter PDMS gradient at surface and the degree of PDMS accumulation on PTFE- and silicone rubber-side surfaces were much higher than that on stainless steel-side surface.
