Abstract (en)
[origin: WO9858111A1] A laminate suitable for use as an electrode separator in an electrochemical device is formed from first and second non-woven fabrics which each comprise fibres of a hydrophobic polymeric material. The first fabric is formed from spun fibres and the second fabric is a melt-blown fabric. The fibres of the fabrics have undergone a copolymerisation reaction with a vinyl monomer which is capable of reacting with an acid or a base to form a salt directly or indirectly such as acrylic acid. The reaction involves exposure of the laminate to ultraviolet radiation while impregnated with a solution of the vinyl monomer, and results in grafting of the vinyl monomer to the surfaces of the fibres.
