제목 Pore selective functionalization in porous honeycomb-patterned films: Breath figure process accompanying interfacial chemical reaction
초록 Fabrication process for the pore-selective functionalization of honeycomb-patterned (HCP) films is demonstrated by a modified breath figure method accompanying an interfacial chemical reaction. Differently from the breath figure (BF) process fabricating a porous HCP films under humid conditions, a chemical reaction is accompanied with the BF process. Wherein, the polymer solution containing reactant A is cast under humid conditions containing reactant B to facilitate a chemical reaction at condensed polymer solution interface, which results in pore-selective functionalization by C. By using this method, many organic or inorganic functional materials such as PANI, SnS, CdS, PS-COOH were pore selectively functionalized. For example, PS solution containing SnCl2 is cast under humid conditions containing aqueous H2S for the formation of SnS functionalized PS HCP films. H2S humidity was generated by pumping ambient air through aqueous Na2S solution.
