Modifications of Polymers: Hydrophobicity and Hydrophilicity

Abstract

This study evaluates the effect of non-thermal plasma treatment on the surface properties of two polymers commonly used in biomedical applications: polylactic acid (PLA) and polycarbonate (PC). Polymer samples were fabricated using 3D printing and exposed to plasma for different time intervals. After treatment, the samples were immersed in simulated body fluid (SBF) to evaluate surface changes. Surface modifications were analyzed using microscopy and surface characterization techniques. The results suggest that plasma exposure increases surface roughness and hydrophilicity, which may enhance protein adsorption and cell adhesion, making these materials more suitable for biomedical and tissue engineering applications.
