Kind Code:
A1
Abstract:
The present invention relates to a biodegradable coating composition, a method for preparing same, and a biodegradable article using same. Particularly, according to an embodiment of the present invention, a biodegradable coating composition is a copolymerized polyhydroxyalkanoate (PHA) resin comprising a PHA resin, a surfactant, inorganic particles and a rheology modifier, and including 4-hydroxybutyrate (4-HB) repeating units. By using a PHA resin having a weight average molecular weight of 10,000-1,200,000 g/mol, the biodegradable coating composition is environmentally friendly due to excellent biodegradability and biocompatibility, and can have improved dispersibility, coatability, oil resistance and processability.
