Abstract
Chitosan/polycaprolactone (Ch/PCL) semi-natural polymeric blend containing gradient concentrations of CdSe quantum dots (QDs) dopant were synthesized via hot injection method. Synthesized samples containing different concentration of CdSe QDs were characterized by X-ray diffraction and FTIR absorption spectroscopy. FTIR experimental data of synthesized samples shows the maintenance of characteristic vibrational band with a marginal variation in both intensity and position related to the increase in dopant concentration. XRD patterns reveal amorphous nature of prepared virgin blend and blend samples that contain small amount of QDs. Samples with higher QDs concentration, namely (0.008, 0.016) wt% show appearance of crystalline bands related to the (1 1 1) reflection plane and in agreement with JCPDS card no. 19-0191. Scanning electron microscopy (SEM) indicates that morphology of synthesized bio-composites is critically affected by addition of CdSe QDs.Antibacterial tests reveals different inhibition zone related to increasing concentration of CdSe QDs and type of bacteria under investigation. Evaluation of The activity index % were also studied.
