Abstract
The present inventive concept provides a self-healing copolymer or self-healing block copolymer, a method of preparing the same, and a film comprising the same. The self-healing copolymer is a copolymer containing three or more types of monomers such as a methacrylate-based compound as a first monomer, an acrylate-based compound as a second monomer, and] N-2-(phthalimido ethyl methacrylate) (NPEMA), phenyl methacrylate (PMA) or N-(4-hydroxyphenyl)methacrylamide (HPMMA) as a third monomer. The self-healing block copolymer is a block copolymer comprising a self-healing random copolymer containing three or more types of monomers and a styrene-based compound polymerized at the end of the self-healing random copolymer. The film comprising the self-healing copolymer or self-healing block copolymer can self-heal at low temperature or at room temperature in the event of structural damage such as cracks and scratches formed on the surface without the need for additional processes, thereby offering excellent utility in various applications.
