AB  - Organic-inorganic materials have been widely utilized in various fields as 
      multifunctional materials. Poly(dimethyl siloxane) (PDMS), a typical inorganic 
      polymer, has industrially appealing functions, such as transparency, 
      biocompatibility, and gas permeability; however, it has poor mechanical 
      properties. We incorporated organic-inorganic hybrid elastomers 
      (PDMS-gammaCD-AAl supersetP(EA-HEMA) (x)) with movable crosslinks, and we utilized hydrogen 
      bonds as reversible crosslinks. The organic polymer poly ethyl acrylate-r-hydroxy 
      ethyl methacrylate (P(EA-HEMA)) penetrated the cavity of triacetylated 
      gamma-cyclodextrin (gammaCD), which was introduced into the side chains of PDMS, and it 
      compounded with PDMS at the nanoscale. Structural studies involving visual and 
      X-ray scattering measurements revealed that movable crosslinks improved the 
      compatibility levels of PDMS and acrylate copolymers. However, macroscopic phase 
      separation occurred when the number of reversible crosslinks increased. 
      Furthermore, studies on the mobility levels of acrylate copolymers and movable 
      crosslinks indicated that the relaxation behaviour of PDMS-gammaCD-AAl supersetP(EA-HEMA) (x) 
      changed with changing numbers of reversible crosslinks. Introducing reversible 
      crosslinks improved the Young's modulus and toughness values. The movable and 
      reversible crosslinks between the organic and inorganic polymers contributed to 
      the high elongation properties. The design of PDMS-gammaCD-AAl supersetP(EA-HEMA) (x) 
      incorporated cooperatively movable and reversible crosslinks to achieve high 
      compatibility of immiscible polymers and to control the mechanical properties.
