【摘要】We report on the effects of aggregation of P3HT with ordered conformation in solution on improving the uniaxial alignment of the P3HT nanofibers by zone casting.Two approaches were employed to change the aggregation of P3HT:P3HT blending with coil insulating polymer and ultrasonic oscillating.The insulator polymer (i.e.PS) which has good solubility in the solution would disturb the aggregation of P3HT to prevent the chains entanglement.The ultrasonic oscillation can further improve the P3HT aggregation with ordered conformation in the solution.As a result,the P3HT nanofibers in the film grew much orientedly by zone casting the ultrasonic oscillating P3HT/PS polymer blends solution than the same solvent P3HT solution without ultrasonic oscillating and blending.The P3HT π-π stacking direction is parallel to the alignment direction of the nanofibers.Meanwhile,the P3HT/PS blend ratio and PS molecular weight have influence on the uniaxial alignment of P3HT nanofibers.Only P3HT/PS is 1∶1,the P3HT nanoflbers oriented well.The low molecular weight PS can make the P3HT nanoflbers orient

better than that of the high molecular weight. 【总页数】5页(23-27) 【关键词】
