Abstract
The present disclosure relates to a composite material including a polyester-carbonate copolymer and nanochitin. The composite material has an advantage in that it is suitable for use as an environmentally friendly material due to excellent biodegradability by the ester group in the copolymer, and the problem of deterioration of properties during storage and use can be minimized because hydrolysis resistance is improved by the carbonate group in the copolymer and nanochitin.
Claims16
A composite material comprising:
- a polyester-carbonate copolymer and nanochitin,
- wherein the polyester-carbonate copolymer is a copolymer of a dicarboxylate-based monomer, a carbonate-based monomer, and a diol-based monomer.
A method of manufacturing a composite material, comprising:
- preparing a nanochitin dispersion (S10);
- mixing the nanochitin dispersion, a dicarboxylate-based monomer, a carbonate-based monomer, and a diol-based monomer to produce a monomer composition (S20);
- and
- copolymerizing the monomer composition using an in-situ polymerization method to produce a polyester-carbonate copolymer (S30).
