Material Solution

Using a thermally-crosslinkable organosiloxane-based organic-inorganic hybrid material, solution-processable gate dielectric layer for organic thin-film transistors (OTFTs) have been fabricated. The hybrid dielectric was synthesized by the sol-gel process. The surface of the prepared dielectric was modified by self-assembled monolayers (SAMs) treatment using wet chemical method. Prior to surface modification, the chemical inertness of prepared dielectric was investigated by immersing into various solvents such as toluene, acetone, isopropyl alcohol, and DI-water. The existence of SAMs on the surface of dielectric was confirmed by measuring current density-electric field characteristics and it was observed that surface morphology of SAMs-treated hybrid dielectric was very smooth.

Shape Memory Polyurethane

Shape memory polyurethane (SMPU)/Vapor grown carbon nanofibers (VGCNF) composites with different surface functionalized method were prepared via sol-gel process. The structure and properties of the composites were investigated by scanning electron microscopy (SEM), universal testing machine, and dynamic mechanical analysis (DMA). The results show that the dispersion of VGCNF with surface modification in matrix is better than that of pristine. The mechanical properties of the composites with VGCNF modified by concentrated nitric acid deteriorated substantially. However, both the tensile strength and elongation at break of the composites combined surface modification of silane coupling agent and sol-gel method increased obviously. The substantially improved mechanical properties are mainly attributed to the cross-link between coupling agent and the network structure of SiO2produced during the sol-gel process. The DMA analysis suggests that the surface treatment of the VGCNF exhibit obviously effect on the dynamic mechanical properties of the composites.

Sol Gel Process

We attempted surface modification in ZnO nanoparticles (NPs) synthesized by the sol–gel process with polyvinyl pyrrolidone (PVP) applied to bulk-heterojunction polymer solar cells (PSCs) as an electron transport layer (ETL). In general, ZnO NPs have trap sites due to oxygen vacancies which capture electrons and degrade the performance of the PSCs. Devices with six different PVP:Zn ratios (0.615 g, 1.230 g, 1.846 g, 2.460 g, 3.075 g, and 3.690 g) were fabricated for surface modification, and the optimized PVP:Zn ratio (2.460 g) was found for PSCs based on P3HT/PCBM. The power conversion efficiency (PCE) of the fabricated PSCs with PVP-capped ZnO exhibited a significant increase of approximately 21% in PCE and excellent air-stability as compared with the uncapped ZnO-based PSCs.
