The results show that the glass-ceramics with fibroid structure is produced after definite heat treatment, the main crystallization phase is hedenbergite and anorthite is the minor crystallization phase. The optimal process of heat treatment shows as follows: the nucleation temperature is 850 ℃ and hold time is 100 min, and the crystallization temperature is 980 ℃ and hold time is 80 min. With increasing heat treatment temperature, the FT-IR absorption bands appear obvious split, the aluminum-oxide polyhedron in the glass network changes from [AlO4] to [AlO6]. The titanium ion in the glass network gradually transforms to the 6-coordinated, moreover forms minicrystal of MgTi2O5 and Fe2TiO4 which provides the position of heterogeneous nucleation for the growth of crystal.

The analysis of polymer structure indicates that the non-crystalline phase is the majority of the agglomerate structure and the crystalline phase is the minority, the highest crystal value only reaches the level of 0.1646;There is a definite interactionadditives and PVA, which not only reduces the crystal value of ASPE to make amorphous areas enlarge but also improve the ability of segmental motion by destroying the well-regulated and orderly character of polymer chain, meanwhile restricts the mobility of potassium cation and enhances the anionic transference number of hydroxide ions, all these improve the ionic conductivity;The ionic conductivity occurs essentially within the amorphous phase of the ASPE;The structure of ASPE doesnt change in the range of our test temperature, this means, the temperature only takes effect on degradation of complex in certain compositions, ionic mobility and segmental motions of the polymer chain.
聚合物结构分析表明:碱性固体聚合物电解质中凝聚态结构以非晶态为主,仅有少量的晶态,结晶度最大为0.1646;添加的各组分与PVA之间都有一定的相互作用,这种作用不仅破坏了聚合物链段的规整性,能够降低聚合物的结晶度,增大无定形区域,提高链段运动的能力,同时这种作用限制K~+离子的运动,提高OH~-的迁移率,从而提高离子电导率;碱性聚合物电解质的离子传导主要发生在无定形区;在本实验测试离子电导率温度范围内,聚合物内部的结构不会发生变化,即温度只会影响电解质内部络合物解离程度和载流子迁移以及聚合物链段运动的情况。
