“…Recently Lai et al reported on plasma treatment of commercially available PTFE membranes [283]. The membranes were exposed to various N 2 /H 2 plasmas in a dose matrix, and it was shown that although the surface of the membrane was rendered hydrophilic, the performance was changed and the energy cost reduced.…”

Membrane distillation is a process that utilizes differences in vapor pressure to permeate water through a macro-porous membrane and reject other non-volatile constituents present in the influent water. This review considers the fundamental heat and mass transfer processes in membrane distillation, recent advances in membrane technology, module configurations, and the applications and economics of membrane distillation, and identifies areas that may lead to technological improvements in membrane distillation as well as the application characteristics required for commercial deployment.

“…However selection of a thicker membrane decreases both the flux and permeability. One promising approach may be selection of a membrane with higher porosity since thermal conductivity of polymer membrane is significantly higher than thermal conductivity of water vapour in the membrane pores (Brodard et al, 2003;Bryjak et al, 2000;Chanachai et al, 2010;Huo et al, 2010;Kong et al, 1992;Krajewski et al, 2006;Lai et al, 2011;Li & Sirkar, 2004;VargasGarcia et al, 2011;Wu et al, 1992;Yang et al, 2011b) have been attempted until now. However, there is very limited number of studies on the design of MD membranes (Khayet, 2011;Khayet et al, 2010;Phattaranawik et al, 2009;Wang et al, 2009;Yang et al, 2011a).…”

“…Surface morphology study reveals the appearance of parallel pore layers during plasma treatment. Plasma treatment deploys contact angle as a function of treatment time [13]. The bipolar Argon plasma treatment of PTFE also supports the same as with plasma treatment there is an increase in surface free energy [14].…”

High-performance commodity polymers are in demand due to low cost, durability, easy productivity, and recycling ability. This article comprises a survey on the performance properties of polytetrafluoroethylene (PTFE) fluoropolymer. It is a well-known choice for coatings, insulation, thermal sealing, lubrication, bearings, and clinical applications. PTFE was engineered in many forms as a function of loading nano and micro fillers for different purposes and the improved properties and performance were addressed by the researchers. Hence, we disclosed the various casting routes of PTFE which is feasible for reliable processing to serve in domestic and industrial applications.
