TiO2/Silane Coupling Agent Composed Two Layers Structure: A Novel Stability Super-hydrophilic Self-cleaning Coating Applied in PV Panels
Energy Procedia, 2017Co-Authors: Zhong Hong, Hu Yang, Wang Yuanhao, Yang HongxingAbstract:Abstract In order to improve the properties of anti-dust and self-cleaning for PV panels, self-cleaning has been proposed. But traditional self-cleaning Coatings are unstable in nature environment, so it limited the application in the PV panels. Based on the above discussions, this study aims to design a novel super-hydrophilic Coating with high stability and corrosion resistance which would be very advantageous for applying in the PV panels. The super-hydrophilic self-cleaning Coating is composed by 3-triethoxysilylpropylamine (KH550) and TiO2. KH550 is a kind of surface modification agent which creates more active group on surface of glass. Due to the water as the solvent, the Coating is environmental friendly and the material coast is low. This Coating can be applied with spraying technology and Roller Coating by changing the Coating's viscosity. The composition was measured by Fourier transform infrared spectroscopy (FTIR), particle size distribution and the surface structure was characterized by Scanning Electron Microscope (SEM). The water contact angle (WCA) was measured by contact angle instrument. It was found that the static water contact angle on the surface of super-hydrophobic Coating was as lower than 5, which show an excellent super-hydrophilic property.

Formation of Thin, Isoporous Block Copolymer Membranes by an Upscalable Profile Roller Coating Process—A Promising Way to Save Block Copolymer
Membranes, 2018Co-Authors: Thomas Bucher, Volkan Filiz, Clarissa Abetz, Volker AbetzAbstract:In this work we present a method to manufacture flat sheet membranes with a thin isoporous block copolymer (BCP) layer (thickness 95% of BCP raw material compared to common doctor blade casting, by strongly decreasing the layer thickness to below 3 µm in combination with a highly open substructure. Additionally, we report a straightforward method to investigate the influence of the solvent evaporation time between Coating and precipitation (phase inversion) on the membrane morphology using one sample only, which also ensures that all other influencing parameters remain constant.

Formation of Thin, Isoporous Block Copolymer Membranes by an Upscalable Profile Roller Coating Process—A Promising Way to Save Block Copolymer
MDPI AG, 2018Co-Authors: Thomas Bucher, Volkan Filiz, Clarissa Abetz, Volker AbetzAbstract:In this work we present a method to manufacture flat sheet membranes with a thin isoporous block copolymer (BCP) layer (thickness <3 µm) by profile Roller Coating (breadth: 30 cm) on top of a porous support membrane. Highly diluted BCP-solutions were used for this Coating process. While we cast membranes with dimensions of 30 cm × 50 cm in this work, the procedure can easily be extended to endless dimensions in this roll to roll (R2R) process. The method offers the possibility to save >95% of BCP raw material compared to common doctor blade casting, by strongly decreasing the layer thickness to below 3 µm in combination with a highly open substructure. Additionally, we report a straightforward method to investigate the influence of the solvent evaporation time between Coating and precipitation (phase inversion) on the membrane morphology using one sample only, which also ensures that all other influencing parameters remain constant

Tattoolike Polyaniline Microparticle-Doped Gold Nanowire Patches as Highly Durable Wearable Sensors
ACS Applied Materials & Interfaces, 2015Co-Authors: Shu Gong, Lim Wei Yap, Daniel T. H. Lai, Qianqian Shi, Naveen Noah Jason, Tamarapu Sridhar, Hemayet Uddin, Yan Wang, Wenlong ChengAbstract:Wearable and highly sensitive strain sensors are essential components of electronic skin for future biomonitoring and human machine interfaces. Here we report a low-cost yet efficient strategy to dope polyaniline microparticles into gold nanowire (AuNW) films, leading to 10 times enhancement in conductivity and ∼8 times improvement in sensitivity. Simultaneously, tattoolike wearable sensors could be fabricated simply by a direct “draw-on” strategy with a Chinese penbrush. The stretchability of the sensors could be enhanced from 99.7% to 149.6% by designing curved tattoo with different radius of curvatures. We also demonstrated Roller Coating method to encapusulate AuNWs sensors, exhibiting excellent water resistibility and durability. Because of improved conductivity of our sensors, they can directly interface with existing wireless circuitry, allowing for fabrication of wireless flexion sensors for a human finger-controlled robotic arm system.
