中文摘要polyelectrolyte complexes (pecs) of chitosan and phosphotungstic acid have been prepared and evaluated as novel proton-conducting membranes for direct methanol fuel cells. phosphotungstic acid can be fixed within pecs membranes through strong electrostatic interactions, which avoids the decrease of conductivity caused by the dissolving of phosphotungstic acid as previously reported. scanning electron microscopy (sem) shows that the pecs membranes are homogeneous and dense. fourier transform infrared spectroscopy (ftir) demonstrates that hydrogen bonding is formed between chitosan and phosphotungstic acid. thermogravimetric analysis (tga) shows that the pecs membranes have good thermal stability up to 210 degrees c. the pecs membranes exhibit good swelling properties and low methanol permeability (p, 3.3 x 10(-7) cm(2) s(-1)). proton conductivity (sigma) of the pecs membranes increases at elevated temperature, reaching the value of 0.024 s cm(-1) at 80 degrees c.
