dc.description.abstract芳香族聚苯并咪唑(Polybenzimidazole,PBI)是一类具有优异性能的材料,由于它分子链刚性很大且排列较为规整,它具有如下优点:具有较高的玻璃化转变温度和热分解温度、良好化学稳定性和力学性能。PBI纤维多应用于消防员耐高温材料外套,宇航服以及金属制造业等。但由于PBI分子结构的高度刚性及分子间较强的氢键作用,使其在有机溶剂中的溶解性一般都很差,从而导致加工困难,限制了PBI的应用。 负载磷酸的PBI材料用做高温质子交换膜已经引起了科学家们的广泛关注。PBI是一类碱性材料,纯净的PBI材料质子导电率(σ)仅为10-7~10-6Scm-1,需要通过负载酸提高电导率。磷酸是通过酸碱作用...
dc.description.abstractThe aromatic polybenzimidazoles (PBIs) are a group of materials comprising excellent properties. Because of the high molecular rigidity in the backbone, they have advantages as follows: high glass transition temperature, good thermal decomposition temperature, excellent temperature stability, well chemical resistance and good mechanical property. PBI fiber has traditionally been used in firefighte...
