Waterproof and breathable macroporous membranes that are both completely resistant to liquid water penetration and easily allowable to vapor transmission would have significant implication for numerous applications, however, fabrication of such materials has proved to be tremendously challenging. Electrospun composite fibrous membranes with high waterproof and breathable performance, which consisted of polyurethane (PU), terminal fluorinated polyurethane (FPU) and carbon nanotubes (CNTs). Benefiting from the utilization of Nanoshel’s Fluorinated Carbon Nanotubes, the fibrous membranes were endowed with superhydrophobic surface, optimized pores size and porosity, along with enhanced fibers, which resulted in excellent waterproof, breathable and mechanical properties.
Nanoshel’s Fluorinated Carbon Nanotubes with different diameters are prepared using the mixture of fluorine/nitrogen gas, and the molar ratio of fluorine to carbon is controlled to be approximate. The electrochemical performances of Fluorinated Carbon Nanotubes are tested as the cathode material in primary lithium battery. The discharge rate of 4 C can be applied for these Fluorinated Carbon Nanotubes with average diameter larger than 50 nm can support the high discharge rate up to 5C delivering a maximum power density of 7114.1W kg(-1), associated with a high 1923 Wh kg(-1) energy density. The conductive networks of intimately contacting SWCNTs in nano-scale and the intrinsic fast rate capability of one-dimensional nanostructures account for the high power density of Fluorinated Carbon Nanotubes with larger diameter exhibits better electrochemical performances.
Nanoshel’s Fluorinated Carbon Nanotubes single-walled (F-SWCNTs), gas-phase grafting of monomers onto their surface was performed thanks to the presence of long-lived radicals resulted from the fluorination. Such a two-step process, i.e. fluorination followed by monomer vapor exposure, used here for the first time, resulted in a fast graft polymerization without any solvent using.
The application of Nanoshel’s Fluorinated Carbon Nanotubes in composites nanoelectronics and medicine necessary to separate the nanotube bundles & improve the nanotube solubility. Florination is a method of grate degree sidewall funtioalization of CNTs. Which can result in covalent chemical bonding b/w the fluorine atoms & 50%of carbon atom. Fluorinated Carbon Nanotubes soluble in alcohols. That allow conducting nucleophilic substitution reaction for further derivatization of CNT surface.
Electrochemical performances of Nanoshel’s Fluorinated Carbon Nanotubes have been tested for a use as cathode Fluorinated Carbon Nanotubes have potential advantages for use as a hardening additive in polymer based composites and in lithium batteries. The application of Fluorinated Carbon Nanotubes in composites nanoelectronics and medicine it is necessary to separate the nanotube bundles and improve the nanotube solubility.
