  • Method of preparing a polyrotaxane and polyrotaxane
    Patent number: 11248092
    Abstract: In one embodiment the invention relates to a method of preparing a polyrotaxane, said method comprising: performing a radical copolymerization of at least (a) a first polymerizable monomer having a stopper group, and of at least (b) a second polymerizable hydrophobic monomer, wherein said second monomer is complexed by a ring-shaped molecule, and of at least (c) a third polymerizable hydrophilic monomer; wherein during said copolymerization a copolymer threading said ring-shaped molecule is formed, wherein during said copolymerization said first monomer having a stopper group is incorporated into the chain of said copolymer at least partially between the ends thereof, and wherein said stopper groups prevent said ring-shaped molecule from disassembling from the copolymer; and wherein the amount of said first monomer having a stopper group is of from 0.1 mol % to 20 mol % based on 100 mol % of the total amount of polymerizable monomers.
    Type: Grant

  • Nanostructured Composite Materials with Self-Healing Properties
    Publication number: 20210071001
    Abstract: A self-healing composite material includes at least one cross-linked polyrotaxane and at least one organically modified inorganic hybrid material which comprises functional groups (B) or at least one type of surface-modified inorganic particles which have functional groups (B) on their surface. The polyrotaxane is a cross-linked polyrotaxane and at least two of the threaded ring-shaped molecules are cross-linked by linking of the functional groups (A) and (B).
