中文摘要	In this study, a systematic investigation on the tribological properties of two kinds of hydroxyl-terminated polydimethylsiloxane (HTPDMS)-modiﬁed castor oil- based polyurethane/epoxy resin (PU/EP) interpenetrating polymer network composites (IPN) was carried out through a pin-on-disk arrangement under dry sliding conditions. Experimental results revealed that the incorporation of HTPDMS can signiﬁcantly improve the friction and wear properties of PU/EP IPN. Further, it was found that both the friction coefﬁcient and wear loss decreased with increasing content of HTPDMS. The worn surface of the PU/EP IPN matrix and the modiﬁed composites were analyzed using scanning electron microscope and 3D noncontact surface-mapping proﬁler. The as-prepared and worn surfaces of the HTPDMS-modiﬁed PU/EP IPN were also investigated using X-ray photoelectron spectroscopy. The mechanisms for the improvement of tribological properties were discussed.
