Inorganic-organic composite as proton conductive membrane |
| 초록 |
Proton conductive inorganic-organic membranes supported by poly(vinylidene fluoride) pores membrane were prepared from 3-glycidoxypropyltrimethoxysilane and tetraethoxysilane, 1-hydroxyenthane-1,1-diphosphonic acid by the sol-gel method. A flexible proton conductive membrane with relatively high mechanical property was obtained. The thickness was almost 90micrometer and the tensile strength was 28MPa. The proton conductivity could reach 4x10^-3Scm^-1 at 90C when the relative humidity is 90%. The dimensional stability associated with water swelling and temperature and was relatively stable. |
