Functionalization of Carbon Nanotubes for Advanced CNT/LCP Nanocomposites

Sahoo N.G., Cheng H.K.F., Li L., Chan S.H., Zhao J., Nanyang Technological University, SG

A novel approach has been made to the chemical functionalization of multi-walled carbon nanotubes (MWCNTs) for developing advanced polymeric nanocomposites with liquid crystalline polymer (LCP). In the approach, we have selectively introduced two types of [...]

Chemical and Phase Transformations of Nanocrystalline Oxides in a Carbon Nanoreactor

Volodin A.M., Zaikovskii V.I., Bedilo A.F., Klabunde K.J., Boreskov Institute of Catalysis, RU

The application of nanocrystalline oxides as precursors for synthesis of new nanomaterials with the preservation of the dimensions of the initial nanoparticles is of considerable interest. Its main problem is the sintering and growth of [...]

Surface Modification and Performance Analysis of Jute Based Nanophased Green Composite

Hossain M.K., Dewan M.W., Hosur M., Jeelani S., Rangari V., Tuskegee University, US

The surface modification of jute fibers was accomplished by performing subsequent chemical treatments such as detergent washing, dewaxing, alkali and acetic acid treatment. The morphology of the modified surface was examined using the scanning electron [...]

Controlled Dispersion of Carbon Nanotubes Wrapped in Amphiphilic Block Copolymers: Elaboration of Polymer Nanocomposite

Semaan C., Pecastaings G., Schappacher M., Soum A., Laboratoire de Chimie des Polymères Organiques LCPO, FR

The scope of carbon nanotubes (CNT) applications in practical devices has been hampered by poor dispersion and weak interfacial bonding with polymer matrices. Therefore, effective method for CNT dispersion is required for industrial applications. We [...]

Novel Nanoparticles Dispersing Beads Mill with Ultra Small Beads and its Application

Inkyo M., Kotobuki Industries Co., Ltd., JP

We have developed the new type of beads mill and succeeded to solve the many problems for nanoparticles dispersion such as reaglomeration and the damage of crystal structure of nanoparticles. We use the centrifugation technology [...]

Fabrication Processes and Multi-functional Properties of Carbon Nanotube/Inorganic Nanocomposites

Hong S.H., Korea Advanced Institute of Science and Technology, KR

Molecular level mixing process was developed for the fabrication of homogeneous carbon nanotube(CNT)/Inorganic nanocomposites instead of the conventional powder mixing process in order to solve the agglomeration of CNTs and weak interfacial bonding between CNTs [...]

Synthesis and Characterization of Alginate-Based Magnetic Nanocomposite

Luna-Pineda T., Román-Velázquez F., University Of Puerto Rico at Mayaguez, PR

Our work addressed the development of a multi-purpose sorbent consisting of magnetite (Fe304) nanoparticles functionalized by dimercaptosuccnic acid (DMSA) and dispersed into porous calcium alginate beads (CAB). The resultant magnetic nanocomposite (MO-CAB) can be considered [...]

Electric Field Effect on the Rheology of MWCNT Dispersions in Liquid Crystalline Polymers

Cameron-Soto A.R., Acevedo-Rullán A., University of Puerto Rico-Mayagüez, PR

Carbon nanotubes (CNT) are ideal candidates for the development of nanocomposites. Nevertheless, to achieve their potential they should be dispersed and aligned with a specific orientation. Many techniques have been proposed to achieve these requirements [...]

Thermal Analysis of Polyimide-Cobalt Ferrite Nanocomposites

Mazuera D., Perales-Perez O., Singh S.P., Suarez O.M., University of Puerto Rico-Mayagüez, PR

Thermal stability and thermomechanical behavior of new polymer-based nanocomposite was investigated to assess the viability of the fabrication process. The nanocomposite film consisted of a polyimide (PI) matrix and nanodispersoids of a recently developed high-coercivity [...]

In Vivo Toxicity Study of Gold Composite Nanodevices for use in Imaging and Radiotherapy

Khan M.K., Nair B., Kasturirangan V., Kariapper M.S.T., Nigavekar S.S., Toth K., Rustum Y.M., El-Jawahri A., Bizimungu R., Lesniak W., Balogh L.P., Roswell Park, US

We previously reported on the in vitro toxicity assessment of differently charged dendrimer-gold nanocomposites on normal cells (human endothelial cells) and prostate cancer cells (Khan et al., 2008). In this study we evaluate the in [...]
