PTFE/polyamide thin-film composite membranes using PTFE films modified with ethylene diamine polymer and interfacial polymerization: Preparation and pervaporation application

---

Abstract.
Plasma polymerization of ethylene diamine (EDA) on PTFE film surfaces is applied to modify PTFE surfaces
to become hydrophilic and to incorporate amino groups onto PTFE surfaces. The surface-modified
PTFE films are utilized as substrates for interfacial polymerization of EDA and trimesoyl chloride to prepare
PTFE/polyamide thin-film composite (TFC) membranes. The effect of plasma power for plasma polymerization
on the morphology and performances of the PTFE/PA TFC membranes are examined and discussed. The presence of amino groups on the PTFE substrates provides chemical linkages between PTFE and PA layers in interfacial polymerization to make the PTFE/PA TFC membranes are stable for pervaporation separations. A high permeation flux of 1910 g/h m2 and a separation factor of 290 are observed with the PTFE/PA TFC membranes for pervaporation dehydration on a 70 wt% isopropanol aqueous solution at 70 oC. This approach explores a new method to prepare PTFE-based TFC membranes via interfacial polymerizations. The prepared TFC membranes could be potentially utilized in pervaporation and nanofiltration separations.
