From Chlorinated Solvents to Branched Polyethylene: Solvent‐Induced Phase Separation for the Greener Processing of Semiconducting Polymers
نویسندگان
چکیده
Despite having favorable optoelectronic and thermomechanical properties, the wide application of semiconducting polymers still suffers from limitations, particularly with regards to their processing in solution which necessitates toxic chlorinated solvents due intrinsic low solubility common organic solvents. This work presents a novel greener approach fabrication electronics without use Low-molecular-weight non-toxic branched polyethylene (BPE) is used as solvent process diketopyrrolopyrrole-based polymers, then solvent-induced phase separation (SIPS) technique adopted produce films for field-effect transistors (OFETs). The prepared BPE using SIPS show more porous granular morphology preferential edge-on crystalline orientation compared polymer film processed chloroform. OFETs based on similar device characteristics those chloroform thermal annealing, confirming efficiency suitability replace traditional green electronics. new potentially compatible different printing techniques promising preparation layers OFET-based
