Development of polylactic acid polymer with improved thermal and barrier properties

摘要

The present invention is a surface-treated HNT (halloysite nanotube); And PLA (Poly lactic acid); is polymerized, and the surface of the surface-treated HNT (halloysite nanotube) is related to a PLA/HNT composite material in which polyethylene imine is bonded in a layered form. The PLA/HNT composite material according to the present invention may be prepared by surface-treating HNT (halloysite nanotube), and in-situ polymerization of the surface-treated HNT and PLA using a press method. The PLA/HNT composite material of the present invention has high barrier properties and high heat resistance by manufacturing a composite material through In-Situ Polymerization of Halloysite and Poly(lactic acid) (PLA), and has excellent processability because it is eco-friendly and flexible.
