Gel with self-restorability and shape-memory property and process for producing same

Abstract

The present invention provides a gel formed by a host-guest interaction and having self-healing and shape-memory properties, and a process for producing the gel. A monomer containing a host group, a monomer containing a guest group, and an acrylic type monomer were dissolved in an aqueous solvent, and these monomers were subsequently copolymerized to produce a gel obtained from these monomers.

1 . An inclusion complex formed of a host group of a host group-containing monomer and a guest group of a guest group-containing monomer. 
     
     
         2 . The inclusion complex according to  claim 1 , wherein the host group-containing monomer is a monomer represented by formula (1) 
       
         
           
           
               
               
           
         
       
       wherein Q is O or NH, CD is α-cyclodextrin, β-cyclodextrin, or γ-cyclodextrin, and R a  is a hydrogen atom or a methyl group. 
     
     
         3 . The inclusion complex according to  claim 1 , wherein the guest group-containing monomer is a monomer represented by formula (2) 
       
         
           
           
               
               
           
         
       
       wherein A is an optionally substituted aryl group, C(O)OR1, or C(O)NHR1, R1 is an optionally substituted alkyl group, an optionally substituted aryl group, or an optionally substituted arylalkyl group, and R b  is a hydrogen atom or a methyl group. 
     
     
         4 . The inclusion complex according to  claim 1 , wherein the host group-containing monomer comprises a compound having two or more host groups. 
     
     
         5 . A gel comprising the inclusion complex according to  claim 1 . 
     
     
         6 . The gel according to  claim 5 , wherein the gel comprises a host group-containing monomer-derived unit, a guest group-containing monomer-derived unit, and an acrylic monomer-derived unit. 
     
     
         7 . The gel according to  claim 6 , wherein the acrylic monomer is a monomer represented by formula (3) 
       
         
           
           
               
               
           
         
       
       wherein X is OR 2  or NH 2 , R 2  is a hydrogen atom, an optionally substituted alkyl group, or an optionally substituted aryl group, and R c  is a hydrogen atom or a methyl group. 
     
     
         8 . An aqueous solvent solution comprising the inclusion complex according to  claim 1 . 
     
     
         9 . The aqueous solvent solution according to  claim 8 , wherein the aqueous solvent solution comprises a host group-containing monomer, a guest group-containing monomer, and an acrylic monomer.
