3,3′,4,4′-Biphenyltetracarboxylic dianhydride CAS:2420-87-3

He mea nui te 3,3',4,4'-Biphenyltetracarboxylic dianhydride i roto i te hanganga o ngā polymer ātete-mahana teitei, pērā i ngā polyimides me te poly(ether ether ketone) (PEEK). He maha ngā whakamahinga o ēnei polymer i roto i ngā ahumahi rererangi, motuka, hikohiko, me ētahi atu ahumahi nā te mea he tino pumau te pāmahana, he kaha miihini, me te ātete matū. Ka whakamahia hoki te matū hei kaihoko hononga i roto i te hanga kapia epoxy, hei whakarei ake i ō rātou āhuatanga wera me te miihini. Hei tāpiri, ka whakamahia i roto i te hanga rauemi hiko, pērā i ngā polymer tioata wai me ngā polymer semiconducting, nā te mea he kaha ki te whakarato i te pumau pāmahana teitei me ngā āhuatanga hiko ki ngā hua whakamutunga. Hei tāpiri, ka whakamahia te 3,3',4,4'-Biphenyltetracarboxylic dianhydride i roto i ngā rangahau mātauranga me ngā rangahau ahumahi mō te ako i ngā tauhohenga rauropi me te whakawhanake i ngā rauemi hou me ngā āhuatanga kua whakaritea. Nā tōna hanganga matū ahurei me te tauhohenga ka waiho hei wāhanga nui i roto i te whakawhanaketanga o ngā polymer me ngā rauemi matatau me ngā tono kanorau. Hei whakarāpopototanga, he matū te 3,3',4,4'-Biphenyltetracarboxylic dianhydride e whakamahia ana i roto i te hanga i ngā polymer mahi-teitei, ngā kaihoko hononga-whakawhiti, ngā rauemi hiko, me te rangahau mātauranga. Nā ōna āhuatanga matū ahurei ka waiho hei wāhanga nui i roto i ngā tukanga ahumahi me ngā mahi rangahau pūtaiao.
