Abstract

In the present study, stereoregular poly(3-hexylthiophene-2,5-diyl) (P3HT) coated hydroxylated multi-walled carbon nanotubes (MWCNT-OH) nanocomposites were prepared over different reaction times of non-covalent functionalization. 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.

反应时间对P3HT/MWCNT-OH纳米复合材料结构和光学性能的影响

在本研究中，通过不同的非共价官能化反应时间制备了立体规则聚(3-己基噻吩-2,5-二基)(P3HT)包被羟基化多壁碳纳米管(MWCNT-OH)纳米复合材料。反应时间分别为24、48、72、96、120小时。利用傅里叶变换红外光谱(FTIR)和紫外可见光谱(UV-Vis)分析了纳米复合材料的结构和光学特性。随着反应时间的延长，P3HT/MWCNT-OH峰的强度逐渐降低，从而影响了制备的纳米复合材料。与纯P3HT和MWCNT-OH相比，当反应时间达到120 h时，计算得到的复合材料能带隙和乌尔巴赫能分别达到2.60和0.329 eV，呈比例减小。
