چکیده
Confned and unconfned crysallization of poly (3-hexylthiophene) (P3HT) were sudied in the solution-grown supramolecules and melt-grown sysems using a differential scanning calorimeter. The carbon nanotube (CNT), reduced graphene oxide (rGO), their functionalized (CNT-f-COOTh and rGO-f-TAA), and grafted (CNT-g-PDDT and rGO-g-PDDT) derivatives were employed to develop the samples. The absorbance, sructure details via Scherrer formula, fusion enthalpy (ΔHm), and crysallinity (Xc) were measured in two disinct confned/ unconfned crysallization environments. Although the functionalized-CNT/rGO precursors partially reduced the crysallite qualities concerning the prisine CNT and rGO ones in the solution-grown supramolecules, they did not affect the sructural properties in the melt-grown samples. Grafted carbonic materials could be considered as appropriate seeds for the arrangement of P3HTs in both solutions and melt crysallization. The bes absorbances, larger and more compact crysals, higher melting point, ΔHm, and Xc values were recorded for the pre-developed CNT-g-PDDT/P3HT sem-leaf (6.09–22.51 nm, 3.52–13.89 Å, 239.8 °C, 30.86 J/g and 83.40%) and rGO-g-PDDT/P3HT coarse-patched (5.96–20.76 nm, 3.57–13.95 Å, 237.6 °C, 29.13 J/g and 78.73%) supramolecules. Although the melt-grown CNT-g-PDDT/P3HT (201.4 °C, 215.3 °C, 16.22 J/g and 43.84%) and rGO-g-PDDT/P3HT (205.4 °C, 218.8 °C, 18.06 J/g and 48.81%) nanosructures were not as perfect as the respective solution-grown nano-hybrids, they were well-arranged for the CNT/P3HT, CNT-f-COOTh/P3HT, rGO/P3HT, and rGO-f-TAA/ P3HT samples.
