RELEASE AGENT FOR POLYMER COMPOUND, ADHESIVE MATERIAL, AND METHOD FOR USING ADHESIVE MATERIAL

To provide a release agent for a polymer compound which can be used for release of as many kinds of polymer compounds as possible, and can reduce a load required for the release treatment when releasing a polymer compound adhered to an adhesion object; an adhesive material; and a method for using the adhesive material.SOLUTION: As a release agent for a polymer compound which releases the polymer compound adhered to an adhesion object, there is contained a photoresponsive liquid crystal material, a phase structure of which undergoes a transition reversibly between an isotropic phase and a liquid crystal phase by photoisomerization based on irradiation light of different wavelengths. The photoresponsive liquid crystal material is used in a state of being already contained in the polymer compound under a condition where the phase structure of the polymer compound is the isotropic phase when the polymer compound is adhered to the adhesion object. The phase structure of the photoresponsive liquid crystal material is regarded to be capable of undergoing a phase transition from the isotropic phase to the liquid crystal phase by photoisomerization based on light irradiation.SELECTED DRAWING: Figure 1 【課題】極力、多くの種類の高分子化合物の剥離に用いることができ、且つ被接着対象に対して接着される高分子化合物を剥離させるに際して、その剥離処理に要する負担の軽減を図ることができる高分子化合物用剥離剤、接着材料及び接着材料の使用方法を提供する。【解決手段】被接着対象に接着された高分子化合物を剥離する高分子化合物用剥離剤として、異なる波長の照射光に基づく光異性化により相構造が等方相と液晶相との間で可逆的に転移する光応答性液晶材料が含まれている。その光応答性液晶材料は、高分子化合物が被接着対象に接着されるときに、相構造が等方相である下で該高分子化合物中に既に含有された状態で用いられ、その光応答性液晶材料の相構造が光照射に基づく光異性化により等方相から液晶相に転移可能とされている。【選択図】 図１
