Abstract
An electrically-conducting, gas-impermeable, semi-permeable membrane is prepared by impregnating a sheet material of synthetic resin fibres insoluble in water a solution of a polyamide resin in a water-soluble solvent and then leaching the solvent from the impregnated sheet material by washing with water. The sheet material may be stranded, woven or felted, and may be of nylon, acrylonitrile copolymer, e.g. with vinylidene chloride, or vinylidene chloridevinyl chloride copolymer. The impregnation may be by spraying or dipping. The watersoluble solvent may be dimethylformamide, dimethyl sulphoxide, ethylene carbonate, methyl alcohol, ethyl alcohol, propylene carbonate, butyrolactone, isopropyl alcohol or N-methyl-2-pyrrolidone. The products may be used as battery separators. The impregnating solution may also include an ionexchange synthetic resin, in which event the product can be used as a separator membrane in an electrolytic cell, or an antiseptic salt, such as a silver cellulosate or silver polyvinylate, in which event the product is an antiseptic fabric resistant to laundering.
