MD simulation studies of the physical and mechanical properites of P3HT-based blends

In this research, the physical and mechanical properties of semi-crystalline polymerpoly-(3-hexylthiophene-2,5-diyl)-based blends were investigated. The volume versus temperature curves of polymerpoly-(3-hexylthiophene-2,5-diyl)/methano-fullerene derivative[6]-phenyl-C64-butyricacidmethyl ester (P3HT:PCBM) and polymerpoly-(3-hexylthiophene-2,5-diyl)/DOCN-PPV (P3HT/CNPh-PPV) were plotted; however, we obtained one single temperature for each curve between glass transition temperatures of the compounds, which could be considered a good indicator of miscibility. In addition, the Coesif energy density of P3HT, PCBM, and CNPh-PPV were calculated and used to obtain the solubility parameters δP3HT, δPCBM, and δCNPh-PPV. The interaction parameter χ was calculated and used in the investigation and we confirmed the miscibility of our polymer systems. By using the dissipative particle dynamic method, the morphologies of P3HT/PCBM and P3HT/CNPh-PPV were enhanced.The accepted manuscript in pdf format is listed with the files at the bottom of this page.
