“…A great deal of attention is now being placed on inorganic nanomaterials because of their various potential applications in the production of electronic devices, sensors, biochips and energy storage media [3,4,5,6,7,8,9,10,11,12]. Inorganic materials have also been used to form superhydrophobic surfaces [13,14,15].…”

The wettability of reactively sputtered Y2O3, thermally oxidized Y-Y2O3 and Cd-CdO template assisted Y2O3 coatings has been studied. The wettability of as-deposited Y2O3 coatings was determined by contact angle measurements. The water contact angles for reactively sputtered, thermally oxidized and template assisted Y2O3 nanostructured coatings were 99°, 117° and 155°, respectively. The average surface roughness values of reactively sputtered, thermally oxidized and template assisted Y2O3 coatings were determined by using atomic force microscopy and the corresponding values were 3, 11 and 180 nm, respectively. The low contact angle of the sputter deposited Y2O3 and thermally oxidized Y-Y2O3 coatings is attributed to a densely packed nano-grain like microstructure without any void space, leading to low surface roughness. A water droplet on such surfaces is mostly in contact with a solid surface relative to a void space, leading to a hydrophobic surface (low contact angle). Surface roughness is a crucial factor for the fabrication of a superhydrophobic surface. For Y2O3 coatings, the surface roughness was improved by depositing a thin film of Y2O3 on the Cd-CdO template (average roughness = 178 nm), which resulted in a contact angle greater than 150°. The work of adhesion of water was very high for the reactively sputtered Y2O3 (54 mJ/m2) and thermally oxidized Y-Y2O3 coatings (43 mJ/m2) compared to the Cd-CdO template assisted Y2O3 coating (7 mJ/m2).

“…This property was widely exploited in the last years for synthesizing materials for solar energy application. ZnO hybrids materials were prepared employing poly (N-vinylcarbazole) [205,206], poly(phenylene vinylene) copolymers [207][208][209], polyaniline [210], poly(3-hexylthiophene) [211,212], polypyrrole [213], and poly(3,4-ethylenedioxythiophene) [214] as hosting matrices.…”

“…The critical parameters for efficient photo induced charge transfer process are band gap and electron affinities of the polymer as well as of the nanocrystals. The band gap and optoelectronic properties of the inorganic semiconductor nanocrystals and conducting polymers can be modulated by varying size, shape, composition and their side groups and conjugation length respectively [4,5]. Among the inorganic semiconductor nanocrystals, semiconductor oxides such as TiO 2 , Nb 2 O 5, ZnO, PbS, PbSe, CdS, CdSe, CuInS 2 , and CdTe [6][7][8][9][10][11][12][13][14] have been reported for photovoltaic applications due to their possibility to overcome charge transfer limitations in bulk heterojunction cells.…”

This paper reports the synthesis of poly(3-hexylthiophene) (P3HT)/HA@ZnO nanocomposite by in situ polymerization and demonstrates their thermal, morphological and optoelectronic properties. Zinc oxide (ZnO) nanoparticles were prepared by the simple approach of coprecipitation method using zinc acetate dihydrate as precursor modified by hexamine (HA) acting as a capping agent.Structural and photo physical studies shows that conjugated polymer chains intimately contact with the inorganic semiconductor. ZnO has wurtzite structure with average crystallite size of 40 nm. The emission spectra indicate that modified ZnO nanoparticles results in more efficient photo induced charge transfer than that of the simple nanocomposite of P3HT/ZnO. The morphological studies revealed that the transformation of granular morphology of P3HT to the clusters in P3HT/HA@ZnO hybrid nanocomposites. Cyclic voltammeter elucidates the electrochemical behavior and the HOMO-LUMO energy levels of the nanocomposites. The results indicate that the P3HT/HA@ZnO nanocomposite has energy gap of 0.72 eV, indicating this composite has potential for the fabricating hybrid organic-inorganic solid state solar cells. A solar to electric energy conversion efficiency of 0.1238 % was attained with the system.
