Polymerization MWCNT modified with 4-

The nanocomposites obtained firom phenolic resin and carboxylated MWNTs showed an improvement of the thermal stability than the neat phenolic resin. The highest thermal stability was obtained in the case of the nanocomposites obtained by in situ polymerization, due to the quality of dispersion of the functionalized MWCNTs [94]. An enhancement of the thermal stability was also obtained in the case of nanocomposites containing boron phenolic resin and MWCNTs modified with nitric acid, 4,4 -diaminodiphenyl methane and boric acid. This effect was ascribed to better interfacial interactions between modified MWCNTs and the resin matrix [95]. 

The aim of this study was the preparation and preliminary investigation of a polymeric based nanocomposite scaffold modified with multi-walled carbon nanotubes (MWCNT) as materials for bone tissue regeneration. For preparation of the nanocomposite scaffold two types of methods were used, i.e. salt leaching and a combination of salt leaching and gas foaming... 

MWCNTs were modified by grafting with PS using plasma polymerization of styrene mraiomer [166]. The modified MWCNTs were characterized by FTIR, dispersion test, TEM, SEM, and Raman analysis. TEM images of unmodified and modified MWCNTs are shown in Fig. 15. After plasma-induced grafting polymerization, the MWCNTs had a less-tangled organization, which demonstrated that the grafted styrene molecule efficiently promoted dispersal of the MWCNTs. 

A sensor for the detection of Uric acid was proposed in (Yu J.C.C. Lai, 2006) by polymerization of polymethacrylic acid on the surface of vinyl-functionalized CNTs in the presence of the template. The MIP adsorbs more Uric acid than NIP and the imprinting efficiency was found to be about 4.41. The MIP modified MWCNTs can be deposited on the MWCNTs electrode surface and used for the electrochemical detection for the template. The differences of adsorption amounts between MIP and NIP electrodes were determined by CVs with different adsorption times. The adsorption reached saturation after 5min of adsorption and the result was close to the rebinding experiments. The sensitivities of the MIP and NIP modified electrodes were about 11.03 and 5.39 mAM i cm"2, respectively, and the difference mainly came from the affinity cavities which were created by the imprinted template.
