Abstract

The use of Polylactic acid (PLA) has been limited in the biomedical field because of its slow degradation profile which is traceable to its degree of hydrophobicity. In this work, 16.67 wt. % of chitosan (Ch), chitin (Ct) and titanium (Ti-6Al-2Sn-2Mo-2Cr-0.25Si) (Ti) powders weremelt blended with PLA and the resulting composites examined using Fourier Transform Infrared Spectroscopy (FTIR). Chitosan was found to reduce the hydrophobic peak due to δ_s(CH₃) in PLA by 13.92%, chitin by 10.65% and titanium by 8.04%. Summarily, the organic bio-fillers produced more hydrophilic PLA composites than the inorganic filler. The percentage reduction in hydrophobicity renders the developed composites more suitable for orthopaedic applications.
