Thermal-Initiated Hydroxyethyl Methacrylate Functionalization of Multiwalled Carbon Nanotubes

چکیده
Mul t iwa l led-carbon nanotubes (MWCNTs) were functionalized via thermoinitiated free radical polymerization of 2-hydroxyethyl methacrylate (HEMA) using benzoy l pe r ox i de . T ip son i ca t i on was used dur ing the polymerization reaction to separate agglomerated nanotubes. The functionalization was confirmed by control experiments and attenuated total reflectance Fourier transform infrared spectroscopy (ATR-FTIR). Differential scanning calorimetry indicated that the addition of poly(HEMA)-MWCNTs to a two-component polyurethane coating will have little effect on the glass transition temperature of the coating. The poly-(HEMA)-functionalized MWCNTs formed large colloidal structures of highly dispersed nanotubes in both the non-sheared and sheared coatings as determined by atomic force microscopy. This study determined a quick and easy method to functionalize MWCNTs for incorporation into a two-component polyurethane coating. A simple method for producing ordered structures of the MWCNTs via shear observed.

Controlled functionalization of multiwalled carbon nanotubes by in situ atom transfer radical polymerization.
The in situ ATRP (atom transfer radical polymerization) "grafting from" approach was successfully applied to graft poly(methyl methacrylate) (PMMA) onto the convex surfaces of multiwalled carbon nanotubes (MWNT). The thickness of the coated polymer layers can be conveniently controlled by the feed ratio of MMA to preliminarily functionalized MWNT (MWNT-Br). The resulting MWNT-based polymer brus...
متن کاملCharacterization of multiwalled carbon nanotube-polymethyl methacrylate composite resins as denture base materials.
STATEMENT OF PROBLEM Most fractures of dentures occur during function, primarily because of the flexural fatigue of denture resins. PURPOSE The purpose of this study was to evaluate a polymethyl methacrylate denture base material modified with multiwalled carbon nanotubes in terms of fatigue resistance, flexural strength, and resilience. MATERIAL AND METHODS Denture resin specimens were fab...

In this work, an efficient procedure for the functionalization of multiwalled carbon nanotube (MWCNTs) based on nitric acid oxidation was presented. The morphologies of MWCNTs oxidized under various conditions were characterized by scanning electron microscopy (SEM) and Fourier transform infrared spectroscopy (FTIR). The FTIR provided clear evidence for the presence of carboxylic groups (–COOH)...

Film forming, stable hybrid latexes made of methyl metacrylate (MMA), butyl acrylate (BA) and 2-hydroxyethyl methacrylate (HEMA) copolymer reinforced with modified multiwalled carbon nanotubes (MWCNTs) were synthesized by in situ miniemulsion polymerization. The MWCNTs were pretreated by an air sonication process and stabilized by polyvinylpyrrolidone. The presence of the MWCNTs had no signific...
