Study on the Preparation of Polytetraﬂuoroethylene Hollow Fiber Membranes and the Properties

Abstract:

In the present study, Polytetraﬂuoroethylene (PTFE) porous hollow fiber membranes were prepared by PTFE concentrated suspension with the mixture of Poly(vinyl alcohol) (PVA) and Sodium alginate as the fiber-forming carrier. Factors affecting PTFE membrane pore structure and mechanical properties were investigated. Results showed that, (1) the permeation and mechanical properties of the PTFE membrane were influenced significantly by the sintering condition, (2) Morphologies of membranes were observed by scanning electronic microscopy (SEM), fixed sintering state was aided to form the pore structure which was much different from the node-fibril network obtained by PTFE biaxial-stretching process.
