The morphology and effects on the OFET performance of blends of various ratios of P3HT and insulating PLA using CHCl3 and CH2Cl2 as solvents were explored. It is demonstrated that a P3HT network structure within the PLA matrix could be induced using CH2Cl2. The one-dimensional nanowire morphology of these network structures may have provided an efficient pathway for OFET charge transport. These results confirm that P3HT/PLA blends in CH2Cl2 solvent could be used to fabricate low-cost, green-polymer-blended FETs.
