Abstract
Electrically conducting polymers are increasingly being used as NIR fluorescence probes in the area of biomedical engineering via the application of a structural modification process. Peroxydisulphate (PDS) initiated the chemical polymerization process of anthranilicacid (AnA) in a nitrogen atmosphere at a temperature of 0 to 5 oC. Rosebengal (RB) was used as an end capping agent, and vigorous stirring was maintained with and without sand. The produced polymer and its nanocomposite were examined using instruments for UV-visible, TGA, DSC, SEM, EDX, FTIR, CV, FES, HRTEM, and XRD. The thermal stability of the resulting polymers was investigated using non-isothermal degradation kinetics. Additionally, the thermodynamic parameter values were determined. In the 3% weight Sand loaded PAnA system, a conductivity value of 4.31x10− 2 S/cm was recorded, signifying a 90.3% yield percentage. Sand was added, and this resulted in an increase in the rate of polymerization (Rp). The PAnA/Sand nanocomposite system has a higher photo-conversion efficiency of 1.49 percent as compared to the RB end capped PAnA system. The experimental results are scrutinized closely and compared to values reported in the literature.
