A first resin, a curable precursor of a second resin that differs from the first resin, an inorganic material and a solvent are blended and a mixed solution is prepared. Next, by heating the mixed solution, the solvent is removed and the curable precursor is cured, and an organic-inorganic composite is obtained that comprises a composite resin having a co-continuous phase-separated structure formed from a three-dimensionally continuous first phase made of the first resin and a three-dimensionally continuous second phase made of the second resin, and an inorganic material that is localized at the interface between the first phase and the second phase.
摘要:
The invention provides a method for thermally releasing an adherend, which comprises selectively releasing one or some of a plurality of substances adhered on a thermally releasable pressure-sensitive adhesive sheet having a thermally expandable layer containing therein thermo-expandable microspheres, by partly heating the pressure-sensitive adhesive sheet using a heating unit capable of partly heating the pressure-sensitive adhesive sheet. This thermally releasing method may further involve a step of cutting the substance adhered to the pressure-sensitive adhesive sheet. In this occasion, the heating unit has a heating portion of a shape in conformity with the shape of the adherend to be released, and may be provided on at lease one of the side to which the adherend is adhered and the opposite side thereto of the pressure-sensitive adhesive sheet.
