Abstract :
Confined and unconfined crystallizations of poly(3hexylthiophene) (P3HT) were studied in the solutiongrown supramolecules and meltgrown systems using a differential scanning calorimeter. The carbon nanotube (CNT) and reduced graphene oxide (rGO) and their functionalized (CNTfCOOTh and rGOfTAA) and grafted (CNTgPDDT and rGOgPDDT) derivatives were employed to develop the samples. The absorbance, structure details via Scherrer formula, fusion enthalpy ( Delta;Hm) and crystallinity (Xc) were measured in two distinct confined/unconfined crystallization environments. Although the functionalizedCNT/rGO precursors partially reduced the crystallite qualities with respect to the pristine CNT and rGO ones in the solutiongrown supramolecules, they did not affect the structural properties in the meltgrown samples. Grafted carbonic materials could be considered as appropriate seeds for the arrangement of P3HTs in both solution and melt crystallizations. The best absorbances, larger and more compact crystals, and higher melting point, Delta;Hm, and Xc values were recorded for the predeveloped CNTgPDDT/P3HT stemleaf (6.09 -22.51 nm, 3.52 -13.89 Aring;, 239.8 °C, 30.86 J/g and 83.40%) and rGOgPDDT/P3HT coarsepatched (5.96 -20.76 nm, 3.57 -13.95 Aring;, 237.6 °C, 29.13 J/g and 78.73%) supramolecules. Although the meltgrown CNTgPDDT/P3HT (201.4 °C, 215.3 °C, 16.22 J/g and 43.84%) and rGOgPDDT/P3HT (205.4 °C, 218.8 °C, 18.06 J/g and 48.81%) nanostructures were not as perfect as the respective solutiongrown nanohybrids, they were wellarranged with respect to the CNT/P3HT, CNTfCOOTh/P3HT, rGO/P3HT and rGOfTAA/P3HT samples
