研究了碳酸丙烯酯（添加量５％）与γ－丁内酯（添加量１０％）对由数均分子量为８００的聚氧化乙烯（ＰＥＯ８００）大单体交联不饱和聚酯（含ＬｉＣｌＯ４）形成的接枝聚酯网络的离子导电性能影响，发现其电导率主要取决于体系中的ＬｉＣｌＯ４浓度．当［ＥＯ链节］／［Ｌｉ＋］＝３０时，室温电导率达最大值，σ２９８Ｋ＝（４．０—４．５）×１０－５Ｓｃｍ－１．这类接枝聚酯网络的玻璃化转变温度（Ｔｇ）同样取决于盐类浓度，而与网络的交联程度无关．网络中的极性添加剂并不显著影响其交联程度与Ｔｇ，但较大幅度提高离子导电性能，这可能与极性添加剂加速载荷离子在导电通道中的迁移性有关．若在上述接枝网络中引入环氧树脂网络，形成接枝聚合物互穿网络，则成膜后的机械强度有进一步提高，同时具有优良的室温电导率，σ２９８Ｋ＝２．４×１０－５Ｓｃｍ－１。
The effects of propylene carbonate (5%) and γ-butyrolactone (10%) on the mechanical properties of polyethylene terephthalate (PEO800) macromonomer crosslinked unsaturated polyesters (including LiClO4) The ionic conductivity of the resulting grafted polyester network was affected and it was found that its conductivity was mainly dependent on the LiClO 4 concentration in the system. When [EO link] / [Li +] = 30, the maximum conductivity at room temperature, σ298K = (4.0-4.5) × 10-5Scm-1. The glass transition temperature (Tg) of such grafted polyester networks also depends on the salt concentration, regardless of the extent of network crosslinking. The polar additive in the network does not significantly affect the degree of crosslinking and Tg, but greatly enhances the ionic conductivity, which may be related to the polar additive accelerating the migration of loaded ions in the conductive channel. If an epoxy resin network is introduced into the above grafting network to form a grafted polymer interpenetrating network, the mechanical strength after film formation is further improved, and at the same time, it has excellent room temperature conductivity, σ 298K = 2.4 × 10 -5 S cm -1.
