Abstract
This work reports the synthesis and properties of a new membrane based on polyvinyl chloride (PVC) grafting with polyacrylic acid (PAA) using argon (Ar) plasma. The membranes of PVC were synthesized by solution-casting method, where PAA was deposited as an ultrathin film onto PVC using dielectric barrier discharge at atmospheric pressure with Ar gas. The surface characteristics and chemical composition of the modified membranes were analyzed by water contact angle, scanning electron microscopy, and Fourier transform infrared spectroscopy. Moreover, the electrochemical properties of the membrane were investigated via ion exchange capacity for the purpose of using it as a polyelectrolyte membrane.
Highlights
Fuel cells have advantages that have made them the first source of portable energy used in vehicles and simple buildings as an alternative to rechargeable batteries [1,2]
Abu-Saied et al reported that polyvinyl chloride (PVC) membrane was grafted with polyacrylic acid (PAA) using plasma air/O 2 gas and they observed that a strong polar membrane surface was generated equipped with -COOH groups
The methanol uptake % results in comparison to other research (Table) showed that the relevant values of the PVC membrane modified by Ar plasma followed by grafting with PAA are much better than those prepared from different molar ratios of PEC and PAA
Summary
Fuel cells have advantages that have made them the first source of portable energy used in vehicles and simple buildings as an alternative to rechargeable batteries [1,2]. An important application of fuel cell systems in proton exchange membranes was the new generation of vehicles with PEMFCs in 1993 in the United States [3]. Dielectric barrier discharge (DBD) is a good example of one of the best types of plasma active in atmospheric conditions [20] It is a heterozygous secretion and needs little energy and alternating voltage. Abu-Saied et al reported that polyvinyl chloride (PVC) membrane was grafted with polyacrylic acid (PAA) using plasma air/O 2 gas and they observed that a strong polar membrane surface was generated equipped with -COOH groups. The grafting of PVC membrane with PAA to improve the characteristics of fuel cell applications is reported. Amination and sulfonation processes are done after grafting to improve the electronegativity of the PVC surface, which may accelerate the attraction of protons in the fuel cells
