Growth and characterization of hybrid (HoGO/P3HT) graphene-based nanostructures for photovoltaic (PV) applications.
摘要： Herein, we present a comparative study between nanostructures of poly(3-hexylthiophene) (P3HT), Holmium-Graphene Oxide (HoGO) nanocomposite and hybrid HoGO/P3HT thin-film nanostructures in terms of structural, morphological and spectroscopic properties. Specifically, the graphene based GO nanostructure was functionalized with rear earth ion Ho(III) to improve its mobility. Furthermore, semiconducting P3HT nanostructure was successfully grown with HoGO nanocomposite creating hybrid HoGO/P3HT nanostructure for energy materials. The nanostructures were characterized by X-ray diffraction (XRD), Scanning Electron Microscopy (SEM), (FTIR) and UV/VIS/NIR spectroscopy. The interaction between HoGO and HoGO/P3HT nanostructures is evidenced through substantial variations in nanoparticle morphologies. FTIR results provided the evidence of the presence of different types of carbon functionalities in the nanostructures. From the absorption spectra, growth of hybrid HoGO/P3HT nanostructure broadened the absorbance with a slight decrease in %. These nanostructures open a promising direction on growth of hybrids for photovoltaic applications because of their interesting optical properties.

Effect of tiny amount of zinc oxide on morphological and thermal properties of nanocomposite PEBA thin films
摘要： Novel PEBA-based nanocomposite thin films were prepared with different low concentrations of ZnO and characterized by AFM, FTIR, FESEM, DSC and TGA. AFM images indicated that the surface roughness of films increased by ZnO loading. FTIR spectroscopy revealed interaction between PEBA polymer and ZnO nanoparticles: The results presence of physical showed that ZnO nanoparticle undergoes an interaction with the CAOAC groups of the PEBA soft segments. DSC analysis showed that incorporation of ZnO caused substantial influence upon the thermal transition of the polyether domain of polymer. TGA showed a significant enhancement of the film thermal properties with ZnO loading. The loading of 0.5 wt% ZnO showed much better dispersion than 1.0 wt% ZnO, while the nanoparticle agglomeration for the latter was observed.
