Cell growth, cell adhesion, and proliferation on biocompatible polymers and polymer-based composites are affected by the surface energy and the interfacial properties. One of the major factors that affect adhesion is contamination by different microorganisms. This contamination and simultaneous growth of microorganisms can affect the quality and quantity of healthy cells that grow on the surface. Polylactic Acid (PLA) is a biodegradable polyester material produced from renewable resources like biomass. Additionally, its biocompatibility has permitted its use in food packaging and the biomedical industry. Despite its benefits, PLA intrinsically lacks strength, durability, and adhesiveness. The current work focuses on mitigating these problems by incorporating surface modification techniques to modulate the surface roughness metrics of PLA. PLA and PLA-based composites were 3D printed and then treated with in-situ corona discharge, a method widely used in a variety of industries because of its safety, low cost, and overall effectiveness.
