- W1505890347 abstract "One kind of acid–base high temperature proton exchange membrane was synthesised from chitosan (CS), 3-aminopropyltriethoxysilane (APTES) and amino trimethylene phosphonic acid (ATMP) by sol–gel process. In order to prevent phosphonic acid from leaching out, ATMP was introduced as proton conductor as well as cross-linker. Fourier transform infrared suggests that the Si–OC2H5 in APTES appears as a hydrolysis–polycondensation yielding Si–O–Si network, and the introduction of ATMP leads to the protonation of the amino group. These membranes are thermally stable up to ∼180°C and show excellent oxidative stability. In addition, the proton conductivity of CS/APTES/ATMP membranes increases with increasing temperature, reaching the value of 0·0578 S cm− 1 at 140°C under normally anhydrous condition, which indicates that the acid–base pair and hydrogen bond network in CS/APTES/ATMP membranes are favourable to proton transfer." @default.
