Nanoshel’s Pristine MWCNT/polyethylene (PE) composites composed of uniformly dispersed, PE-coated MWCNT strands were produced by the in situ polymerization of ethylene with Cp2ZrCl2 immobilized onto the sidewalls of pristine MWCNTs. The prepared composites showed a highly enhanced Young’s modulus (359%) as compared to homopolyethylene.

Nanoshel’s Pristine MWCNTs, used in biomedical applications as considered more biocompatible than pristine MWCNTs, are well defined. Vestigated and compared cytotoxic, genotoxic/oxidative and inflammatory effects of commercial pristine and –OH and -COOH functionalized MWCNTs on human bronchial BEAS-2B cells. The aim was to identify an in vitro experimental model that uses different and complementary end-points to study potential CNT toxicity and to evaluate the role of fictionalization on the induced effects. Cells were exposed to 1-40 μg/mL of each CNT for 24 h. MWCNTs on bronchial cells with higher cyto-genotoxicity for functionalized MWCNTs, no membrane damage and induction of oxidative DNA damage for MWCNT-OH, and inflammatory response for pristine MWCNTs.

Nanoshel’s Pristine MWCNTs have been explored for antibacterial efficacy, but naïve multi-walled CNTs (MWCNTs) still remained unearthed. The investigation of the potential of various non-ionic surfactants in solubility enhancement of MWCNTs and their subsequent antibacterial efficacy against Escherichia coli (E. coli) and Staphylococcus aureus (S. aureus). Polysorbates offer more solubility to MWCNTs vis-a-vis the phospholipids.

The unique properties of Pristine MWCNTs especially Pristine MWCNTs ones, have led to a growing number of applications in electronics and telecommunications. The need for microwave absorbers is ever growing in various applications such as the reduction of electromagnetic interference among electronic components and circuits and reduction of the back radiation of micro-strip radiators. Other areas of application include consumer electronics, wireless LAN devices, radar absorbers, electromagnetic shields, wireless antenna system, cellular phones, and others. Generally, magnetic or metallic particles are used as microwave absorbers.

Carbon nanomaterials including Nanoshel’s Pristine MWCNTs and composite materials based on modi- filed MWCNTs currently attract interest due to their potential applications in heterogeneous catalysis, gas sensors, autoemission devices, electrochemical capacitors, and reinforced composite materials. Different attempts are made in the development of metal and metal oxides deposi- tion methods on the surface of carbon materials and improve- ment of the carbon nanotube/matrix interface properties.
