The reaction time was set as 24, 48, 72, 96, and 120 hours. The structure and optical characteristics of nanocomposites were analyzed using Fourier-transform infrared (FTIR) and ultraviolet-visible (UV-Vis) spectroscopy, respectively. Reaction time affected prepared nanocomposites by decreasing the intensity of the P3HT/MWCNT-OH peaks gradually with increasing of the reaction time. Comparing with the pure P3HT and MWCNT-OH, the calculated energy band gap and the Urbach energy of the nanocomposites were reduced proportionally as the reaction time reached 120 hours and achieved 2.60 and 0.329 eV, respectively.</p>}, number={5}, journal={Polimery}, author={Norizan, Mohd Nurazzi and Abdullah, Norli and Demon, Siti Zulaikha Ngah and Halim, Norhana Abdul and Sa’aya, Nurul Syahirah Nasuha and Mohamad, Imran Syakir}, year={2022}, month={Jun.}, pages={205-211} }
