Synthesize of PCPDTBT nanostructures and PCPDTBT_PC71BM nanocomposite via modified polymer-melt technique

PCPDTBT nanostructures have been synthesized via template-assisted method and polymer-melt technique. The morphological, optical and structural properties of the PCPDTBT have been investigated. Melting polymer was used as a driving force to infiltrate the Anodic Aluminum Oxide (AAO) template in which the applied temperatures are 200, 250, 300, 350, 400 and 450 Celsius respectively. The melting time duration is set constant for 30 minutes for each of those melting temperatures. Nanowires constructions have been produced at all melting temperature however based the morphological investigation, only the first two melting temperatures, 200 and 250, that can serve the structural without any broken noticed on the Raman measurement. The optical and structural properties are also confirm these facts.

Comparison studies between BHBT2:PC71BM composite nanotubes and its bulk-heterojunction properties

In this study, we investigate the morphological, structural, and optical properties of both bulk-heterojunction and composite nanotubes that composed of thiophene-based small molecules BHBT2 and fullerene PC71BM. Mix-blended and template-assisted methods were used to fabricate the bulk-heterojunction and composite nanotubes, respectively. A single material of BHBT2 thin films and nanotubes that fabricated via spin-coating and template-assisted methods, respectively, was also studied. Two different formations between bulk-heterojunction and composite nanotubes were compared to elaborate their advancement in properties. Absorption spectra of BHBT2:PC71BM bulk-heterojunction and composite nanotubes have fallen within the ultraviolet-visible (UV-vis) range. Field emission scanning electron microscope (FESEM) and high-resolution transmission electron microscope (HRTEM) images show that the carbon-rich of PC71BM, has successfully infiltrated into the BHBT2 nanotube to form the BHBT2:PC71BM composite nanotubes. However, due to the informality distribution of infiltration, charge carrier transfer is seen to be better in bulk-heterojunction rather than in the composite nanotubes.
