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).
Claims11
A composition for a self-healing composite material, comprising:
- a) at least one polyrotaxane comprising a copolymer and ring-shaped molecules threaded thereon, with at least one ring-shaped molecule having at least one functional group (A);
- b) at least one organically modified inorganic hybrid material which comprises functional groups (B), or at least one kind of surface-modified inorganic particles which on their surface have functional groups (B);
- where at least two of the threaded ring-shaped molecules can be crosslinked by linking of the functional groups (A) and (B).
