Polylactid acid (PLA) is a type of bio-based and bio-degradable plastic. This substance is commonly used in the medical field since it is biocompatible and does not hurt bodily tissues. In this study, PLA plastic will be combined with chitosan (CS) via injection molding. The addition of CS to compensate for the absence of PLA with hydrophobic characteristics. CS has hydrophilic characteristics, which allow it to absorb water and bond with biological tissues. The contact angle test revealed that pure PLA is a hydrophobic material, but the PLA: CS alloy is a hydrophilic alloy. © 2023 Trans Tech Publications Ltd, All Rights Reserved.
