Abstract
The influence of TEOS on the rheological properties of PVDF and poly(vinylidene fluoride-co-hexafluoropropylene) was investigated. The addition of TEOS to low molecular weight PVDF results in pseudoplastic behavior. The exception is PVDF containing 5 wt%. TEOS, which shows dilation behavior. Similar behavior has high molecular weight PVDF with the addition of 2 wt.% TEOS and low molecular weight copolymer with and without TEOS. The influence of temperature on the viscosity and activation energy of the tested PVDF solutions and the influence of TEOS on the average molecular weight were also examined.
研究了 TEOS 对 PVDF 和聚(偏氟乙烯-共六氟丙烯)流变特性的影响。在低分子量 PVDF 中添加 TEOS 会导致假塑性行为。但含有 5 wt% TEOS 的 PVDF 例外。TEOS 的 PVDF 出现了扩张行为。添加 2 wt.% TEOS 的高分子量 PVDF 以及添加和不添加 TEOS 的低分子量共聚物也有类似的行为。此外,还研究了温度对测试的 PVDF 溶液的粘度和活化能的影响,以及 TEOS 对平均分子量的影响。
