We introduce a stencil mask method to fabricate metallic patch arrays on the electrostrictive poly(vinylidene fluoride–trifluoroethylene) copolymer films. The resulting frequency selective surfaces exhibit resonance responses in the infrared region. Furthermore, the resonant frequency can be tuned by the strain change in the copolymer films. The results demonstrate that the stencil mask method is useful for depositing metallic patterns on a subset of substrates such as polymers that would be damaged by solvents used in conventional photolithography techniques.

    A mean-field theory of globules of random amphiphilic copolymers in selective solvents is developed for the case of an annealed copolymer sequence: each unit can be in one of two states, H (insoluble) or P (soluble or less insoluble). The study is focussed on the regime when H and P units tend...
