Electrospun Poly(γ-glutamate)/Silica Hybrids for Tissue Regeneration: Influences of Silane Coupling Agents on Chemistry, Degradation and Florescent Dye Release

[Silane coupling agents].

Surface Reactions on Thin Layers of Silane Coupling Agents

The reactivity of immobilized functional groups in thin layers of (3-aminopropy1)triethoxy~ilane (APS), (3-mercaptopropyl)trimethoxy~ilane, (3-bromopropyl)trimethoxysilane, and (8-bromoody1)trimethoxysilane on oxidized aluminum substrates was studied with reflection-adsorption infrared spectroscopy (RAIR), optical ellipsometry and contact-angle measurements. Mass changes on the surface associat...

Synthesis and antimicrobial activity of quaternary ammonium silane coupling agents.

Fourteen novel silane coupling agents with a quaternary ammonium group introduced into the molecule, [CH(2)=CHCH(2)N(+)(CH(3))(C(n)H(2n+1))(CH(2))(3)Si(OCH(3))(3)]X(-) (n-X, n=10-18, X=Cl, Br, or I), were synthesized with the aim of using these agents to make material surfaces antimicrobial for a long period of time. Measurements of the minimum inhibitory concentrations (MIC) against 12 kinds o...

Preparation of polyacrylonitrile – titania electrospun nanofiber and its photocatalytic dye degradation ability

In this paper, polyacrylonitrile PAN - titania TiO2 electrospun nanofiber PAN/TiO2 nanofiber was prepared via a facile electrospinning method. The characteristics of the PAN/TiO2 nanofiber were investigated using SEM and FTIR. The nanofiber showed retained nanofiber structures and high photocatalytic efficiency under UV light for the degradation of Direct Red 80 DR80 and Direct Red 23 DR23 in w...
