Surface modification. II. Functionalization of solid surfaces with vinylic monomers

Self-assembling of cyano- and carboxyl-terminated monolayers using short-chain alkylsiloxane

“…But after annealed at 150 8C for about 2 h, it reaches a steady value of 58 AE 28 for advancing and 52 AE 28 for receding contact angle, which is in good agreement with reference [8] [glass/ Si(CH 2 ) 3 CN, 56 AE 28] but not agrees with 728. This is because there are only two methylene groups in our system, according to Wasserman et al [9], the water contact angle drops dramatically when the chains are very short.…”

“…Cyanoterminated monolayer was deposited on the glass substrate by using a 16-carbon, trichlorosilyl surfactant (synthesized from v-hexadecenyl bromide) as a dilute solution in dicyclohexyl by Balachander and Sukenik [7]. It can also be easily prepared by v-cyano alkyl trichlorosilane [8]. Carboxyl-terminated SAM on silica substrate is difficult to be produced since the silane derivative in this case would have polar moieties at both ends and make it difficult to develop a uniform monolayer on the surface.…”

Encapsulation of silica nanoparticles by redox-initiated graft polymerization from the surface of silica nanoparticles

“…For example, modification of aminated silica nanoparticles with α,β-unsaturated carbonyl compounds [39], reaction with methyl acrylate as the first step for the construction of polyamidoamine dendrimers [40] and introduction of peroxide groups capable of initiating graft polymerization [41] onto silica surfaces have been reported preciously.…”

Probing Liquid–Solid and Vapor–Liquid–Solid Interfaces of Hierarchical Surfaces Using High-Resolution Microscopy

“…These studies are useful because many surfaces found in nature possess patterns that are hierarchal and fractal in nature. , In nature, many surfaces, for example, the lotus leaf (Nelumbo nucifera) − and “rose-petal-like” , surfaces show how the superhydrophobicity of these surfaces provides integral functions to plants. The biomimicry of such natural surfaces can provide simple but powerful tools for developing new smart materials for a wide range of applications including antifog, highly repellant nonadhesive and resistant biofilms, − and device fabrication. − Whereas the lotus surfaces are known to possess high aSCA and low water adhesion to the leaf surface, the rose petal exhibits high aSCA of water droplets in addition to high surface adhesion. ,,− Therefore, nature allows for differential wetting, and adhesive properties are needed for plants to minimize the negative effects and/or to utilize these tailored surface properties for enhancing their functionality. ,− Further, it is also instructive and important to study the LS interface at the interior of the drop, which may aid in sorting and solving the debate on the roles of the contact line and interior interfacial area on contact angle, adhesion, and contact angle hysteresis.…”
