The present disclosure provides a method for forming a porous colorimetric gas sensing layer. In various embodiments, the method comprises providing a mixture of an organic solvent, a polymer forming material and a gas sensing compound or gas sensing particles. The method additionally comprises depositing the mixture (sprayed or vaporized) on at least a surface portion of a substrate. Thereafter, an atmospheric pressure plasma is applied to the surface portion to form a polymer layer comprising the gas sensing compound or particles. The steps of depositing the mixture and applying the plasma can be repeated multiple times to form a plurality of stacked or superposed polymer layers comprising the gas sensing compound or particles.
