Chemically metallising electrically non-conducting porous substrates - esp. needle felts, etc., by activating substrate surface and adding metallising soln.

摘要

Electrically non-conducting porous substrates, esp. needle felt, nonwovens or open pored foams are chemically metallised by (A) activating the surface of the susbtrate in known manner and (B) adding a volume of a metallising soln., which is smaller than the free pore volume of the substrate, pref. by 10-30%. The substratee is pref. coated with Cu or Ni. The substrate consists of e.g. polyethylene, polyamide fibres or foam. ADVANTAGE - A technically simple, environmentally friendly process.
