Abstract:

 Several new-generation synthetic biodegradable polymers have been developed specifically for biomedical applications in the last two decades. Polycaprolacton PCL was chosen as the polymer matrix in this study because it is known for its ease of synthesis, commercial availability, and excellent biocompatibility. Carbon Quantum Dots CQDs, one of the carbon nanostructures with superior properties, were used as fillers to produce PCL film nanocomposites with improved biotribological properties. The biotribological behavior of Sample of K-CQDs produced from Rosehip K-CQDs filled PCL matrix nanocomposite films containing 0.3 and 2.0 wt.  K-CQDs filler were investigated in sliding against an alumina Al2O3 counterface by a constant loading 2.5 N and sliding speed 1.7 cm s-1 experiments carried out in a reciprocating friction testing machine in 0.154 M isotonic salt solution. PCLK-CQDs-2.0 film had lower friction coefficent value 0.304 with a 70 decrease, and wear rate 0.00051 mm3Nm; 65 decrease compared to PCLK-CQDs-0.3. The surface images of PCLK-CQDs-2.0 film after the wear test indicated that the wear width trace and the adhesive wear traces decreased. In addition, the absence of cracks on the worn surface showed that both films were resistant to plastic deformation.
