<p>A non-woven fabric is formed from fibres which are substantially unbonded. Copolymerised to the surface of the fibres a vinyl monomer is capable of reacting with an acid or a base to form a salt directly or indirectly by a reaction which involves exposure of the fabric to ultraviolet radiation while impregnated with a solution of the vinyl monomer. The fabric is suitable for use as an electrode separator in an electrochemical device.</p> |
