Abstract

PURPOSE: After high-polymer films swollen with a poor solvent are supported, the solvent is removed, thus producing wrinkle and undulation-free and uniform tense films with high element sensibility and accuracy.
CONSTITUTION: A high-polymer film is swollen by adding a poor solvent or liquid which does not dissolve the polymer and supported on a supporter. Then the solvent or liquid is removed to shrink the film. The high polymer used is, e.g., a thermoplastic resin as polyvinyl chloride, nylon, etc., thermosetting resin as epoxy resin, heat-decomposing resin as polyvinyl alcohol or polyacrylonitrile or natural resin as natural rubber. The inorganic substance added is, e.g., pyroelectric, piezoelectric, electrolytically emitting or magnetic particles.
EFFECT: The present invention can be applied to almost all of the high polymers.
