Influence of the amorphous phase and preceding solution processing on the eutectic behaviour in the state diagram of P3HT : PC 61 BM determined by rapid heat–cool calorimetry Vrije Universiteit Brussel
Rapid Heat-Cool calorimetry was used to determine the state diagram of P3HT:PC61BM mixtures. A particular focus was given to the determination of the eutectic composition and temperature. P3HT was fractionated in three different narrow molecular weight fractions (14.9 kg.mol-1, 32.4 kg.mol-1, 89.1 kg.mol-1) in order to study its effect on the eutectic behaviour. Heating rates of 500 K.min-1 were utilised to drastically decrease or suppress cold ...
