Abstract

In a composition including polyrotaxane and a utilization object thereof, the water molecules are difficult to mix, thereby suppressing the generation of a hydrolysis reaction, and improving the wet resistance. The composition including polyrotaxane comprises a polyrotaxane (A) which includes cyclodextrin as a ring molecule and polyethylene glycol as a linear molecule, and in which a blocking group is arranged at both ends of the linear molecule; a block copolymer (B) including polysiloxane; and a polymer (C) including no polysiloxane. In a curing body formed by the composition, a plurality of annular molecules of the polyrotaxane are combined by a crosslinking part, at least a part of the crosslinking part is the block copolymer (B) having the polysiloxane. A dielectric medium attached with an electrode layer uses a curing film formed by the curing body as the dielectric medium, and electrode layers are attached to the two surfaces of the curing film respectively. An actuator uses the dielectric medium attached with the electrode layers.

Description

technical field [0001] The present invention relates to a composition containing a polyrotaxane, a cured body, a cured film, a dielectric sheet with an electrode layer, and an actuator using the composition. Background technique [0002] A polyrotaxane is an aggregate of molecules having a structure in which a linear molecule relatively slides through a cyclic molecule, and the cyclic molecule is hardly detached due to capping groups arranged at both ends of the linear molecule , which is called the slip ring material. Cyclic molecules and linear molecules are known as various polyrotaxanes, but cyclodextrin is often used as the cyclic molecule and polyethylene glycol is used as the linear molecule (Patent Document 1). [0003] Patent Document 2 discloses a polyrotaxane crosslinked via a cyclic molecule. It is characterized in that it has 10 or more repeating units in its crosslinking part, and / or has a number average molecular weight of 1000 or more, and does not contain ...
