Abstract: A method for making a conductive polymer composite for detecting a gas includes forming a porous conductive layer of a conductive powder on a substrate, applying a polymer solution containing a solvent and a gas responsive polymer material dissolved in the solvent to the porous conductive layer such that a portion of the polymer solution penetrates into the porous conductive layer and the remainder of the polymer solution forms a thin film covering a top of the porous conductive layer, the gas responsive polymer material being capable of adsorbing and desorbing the gas, and removing the solvent from the polymer solution so as to form a polymer matrix covering the porous conductive layer.

Abstract: A method for forming a metal pattern on a substrate via printing and electroless plating is disclosed, which includes printing a pattern on the substrate with an ink composition, drying the printed pattern, and contacting the dried pattern with an electroless plating solution. The ink composition either contains components (i), (ii) and (iii), components (i) and (iv), or components (i) and (v), which are dissolved or dispersed in a solvent, wherein (i) is a binder; (ii) is a sulfate terminated polymer of an ethylenically unsaturated monomer; (iii) is a catalytic metal precursor; (iv) is a polymer of an ethylenically unsaturated monomer deposited with particles of catalytic metal; and (v) is a copolymer of an ethylenically unsaturated monomer and a hydrophilic monomer deposited with particles of catalytic metal. The binder (i) is a water swellable resin. The catalytic metal may be Au, Ag, Pd, Pt or Ru.

Abstract: A copolymer deposited with particles of catalytic metal is disclosed in the present invention, which is formed from an ethylenically unsaturated monomer and a hydrophilic monomer, and the catalytic metal is Au, Ag, Pd, Pt or Ru.

Abstract: The present invention discloses a two-stage process for preparing functionalized magnetizable microspheres. The first stage includes forming an inner shell of styrene polymer or styrene copolymer around magnetizable nano particles having a monolayer of a non-water-soluble dispersing agent coated thereon. The second stage includes forming an outer shell of styrene polymer or styrene copolymer with sulfate (SO4?) bounded thereto around the inner shell by free radical polymerization. Preferably, nano particles of a noble metal are deposited on the surface of the outer shell. The magnetizable microspheres prepared by the process of the present invention have a size of 100-1000 nm, and the thickness ratio of the inner shell to the outer shell ranges from 10:1 to 1:10.
