Synthesis of Super-hydrophilic Mesoporous Silica via a Sulfonation Route
The surface of mercapto-functionalized mesoporous silica having a highly ordered open pore network was modified into a super-hydrophilic surface through a stepwise sulfonation process involving oxidation and ionization reactions. The initial mesoporous silica was prepared using an acid-catalyzed sol-gel reaction between tetraethoxysilane (TEOS) and 3-mercaptopropyltrimethoxysilane (MPTMS) in th...
متن کاملCondensation and Wetting Behavior on Surfaces With Micro-Structures: Super-Hydrophobic and Super-Hydrophilic
Recently it has become possible to achieve radical manipulation of surface wettability, and wettability is known to play a key role in the retention of condensate and frost melt on heat exchanger surfaces. In this paper we present a review of methods to produce such surfaces, and we describe a super-hydrophobic surface, with a contact angle of 148°, created in our lab. We describe surfaces with...
متن کاملFibronectin Adsorption on Hydrophilic and Hydrophobic Surfaces
Studies have been carried out on the adsorption properties of plasma fibronectin (FN) on hydrophobic and hydrophilic surfaces. The hydrophobic and hydrophilic surfaces used were nonwettable bacteriological dishes and wettable tissue culture dishes, respectively. At low plasma FN concentrations, there was more plasma FN binding to hydrophobic surfaces than to hydrophilic surfaces. Under these co...
متن کاملFabrication of Silicon Nanobelts and Nanopillars by Soft Lithography for Hydrophobic and Hydrophilic Photonic Surfaces
Soft lithography allows for the simple and low-cost fabrication of nanopatterns with different shapes and sizes over large areas. However, the resolution and the aspect ratio of the nanostructures fabricated by soft lithography are limited by the depth and the physical properties of the stamp. In this work, silicon nanobelts and nanostructures were achieved by combining soft nanolithography pat...
متن کاملJanus silica film with hydrophobic and hydrophilic surfaces grown at an oil–water interface†
We report a new methyltrimethoxysilane (MTMS) based route to growing a Janus silica film at the oil–water interface, which upon drying shows anisotropic wetting by water on its two surfaces. The contact angle of water on the surface grown in contact with the oil-side is found to be 150 , but it is much smaller, 65 , on the side which grew in contact with the aqueous phase. This large difference...
