Investigation of optoelectronic properties of PNIPAM polymer and its biomedical applications

In this thesis study, the PNIPAM polymer was investigated due to its significant and numerous advantages in biomedical and optoelectronic applications. The electronic and optical properties of the PNIPAM polymer were comprehensively examined. Specifically, important parameters such as the absorption band edge, molar extinction coefficient, optical band gap, refractive index, contrast, optical and electrical conductivity of the PNIPAM polymer were analyzed. The biomedical implications of these parameters were also explored. In particular, the refractive indices of the PNIPAM polymer were optimized for the most suitable biomedical applications. On the other hand, the optoelectronic parameters of the PNIPAM polymer were obtained and compared under different conditions (solvents and dopants). Finally, the effects of UV light at different wavelengths on the optoelectronic parameters of the PNIPAM polymer were investigated. Thus, with the unique and significant findings obtained, the contributions of the PNIPAM polymer to biomedical applications filled relevant gaps in the literature. As a result, PNIPAM and its derivatives have a wide range of applications, from optoelectronic devices to biomedical applications. In particular, the optical properties obtained in UV absorption, visible light transmittance, and NIR regions demonstrate that the polymer is a strategic material for areas such as controlled drug release, sensor technologies, and photothermal applications.
