Surface-initiated Atom Transfer Radical Polymerization and Solution Intercalation Methods for Preparation of Cellulose-G-PS-G-PAN/MMT Bionanocomposite

surface-initiated atom transfer radical polymerization and solution intercalation methods for preparation of cellulose-g-ps-g-pan/mmt bionanocomposite

cellulose was modified by polystyrene (ps) and polyacrylonitrile (pan) via free radical and living radical polymerization, and then cellulose was used as the matrix in the preparation of polymer/clay nanocomposite, through a solution intercalation method. for this purpose, first, the graft polymerization of styrene (st) onto cellulose fibers was performed by using suspension polymerization and ...

Thermosensitive Nanocables Prepared by Surface-Initiated Atom Transfer Radical Polymerization

Thermosensitive nanocables consisting of Au nanowire cores and poly(N-isopropylacrylamide) sheaths (denoted as Au/PNIPAAm) were synthesized by surface-initiated atom transfer radical polymerization (SI-ATRP). The formation of PNIPAAm sheath was verified by Fourier transform infrared (FTIR) and hydrogen nuclear magnetic resonance ((1)H NMR) spectroscopy. Transmission electron microscope (TEM) re...

Facile Preparation of Crosslinked Polymeric Nanocapsules via Combination of Surface-Initiated Atom Transfer Radical Polymerization and Ultraviolet Irradiated Crosslinking Techniques

A facile approach for the preparation of crosslinked polymeric nanocapsules was developed by the combination of the surface-initiated atom transfer radical polymerization and ultraviolet irradiation crosslinking techniques. The well-defined polystyrene grafted silica nanoparticles were prepared via the SI-ATRP of styrene from functionalized silica nanoparticles. Then the grafted polystyrene cha...

Amelioration of Blood Compatibility and Endothelialization of Polycaprolactone Substrates by Surface-Initiated Atom Transfer Radical Polymerization

Monitoring kinetics of surface initiated atom transfer radical polymerization by quartz crystal microbalance with dissipation.

This article reports that the kinetics of surface-initiated atom transfer radical polymerization can be quantified by the quartz crystal microbalance with dissipation (QCM-D) technique. The kinetics of in situ growth of poly(oligoethylene glycol methylmethacrylate) monitored on a gold-coated QCM-D sensor chip revealed that changes in the experimentally observed frequency (DeltaF) and dissipatio...
