This research studied the optical characteristics of PAN-PEG polymeric composite material when titanium oxide (TiO2) nanoparticles were added to it for improving its use for biological purposes. The XRD and FESEM results confirmed the successful fabrication of a PAN-PEG/TiO2 nanocomposite, characterized by well-dispersed and highly crystalline anatase TiO2 nanoparticles. The study examined cooperation of diverse weights of TiO2 nanoparticles (ranging from 0% to 8%) in PAN-PEG composite. The optical characteristics were evaluated across a spectrum of wavelengths spanning from 220 nm to 800 nm. Results of the experiments highlight that absorbance of PAN-PEG composite increases as concentration of TiO2 in the mixture increased. The addition of TiO2 nanoparticle also resulted in a shift in the optical constants and the energy gap of composite. Furthermore, findings of the study revealed potential of PAN-PEG-TiO2 nanocomposites for gamma ray shielding. Overall, study demonstrates the potential of incorporating TiO2 nanoparticles into PAN-PEG polymeric composite for improving its optical as well as shielding properties for variety of applications.
