摘要： 近年来,互穿聚合物网络(IPN)的开发受到了广泛的关注。以聚氨酯为一组分,聚丙烯腈、聚酯及环氧树脂等为另一组分的IPN体系的研究已有报道[1],而聚氨酯与有机硅的IPN体系的研究报道很少[2]。在本文中,我们对聚氨酯(PU)与聚二甲基硅氧烷(PDMS)半IPN的透气性与结构的关系进行了研究。

Abstract: In this paper, the permeability of Polyurethane-Polydimethylsiloxane (PU-PDMS) semi-IPNwas studied. It is found that the gas permeability coefficient Pand the selective separation factors ao2/N2 are determined by the composition of the semi-IPNand the crosslinking density of PDMScomponent. In the midrange composition, Pis equal to 2. 26 × 10-12(cm3·cm/cm2·s·Pa) and ao2/N2 is 3.05.
