Structure and Properties of Aromatic BPDA-PDA Polyimide Fibers under Different Thermal Treatments

摘要：

Polyamic acid (PAA) fibers derived from 3,3,4,4-biphenyltetra-carboxylic dianhydride (BPDA)and p-phenylenediamine (PDA), as shown in Scheme 1, have been fabricated through a dry-jet wet-spinning method.These PAA fibers are thermally treated into polyimide (PI) fibers via two different thermal procedures.In Procedure Ⅰ, PAA fibers were heated from room temperature to different temperatures with a heating rate of 5 ℃/min.And in Procedure Ⅱ, PAA fibers were isothermally treated at different temperatures for different time.
