Single walled carbon nanotubes have special chemical and physical properties, at the same time, they have the advantage of macro maneuverability in maneuverability, so they have the potential of multi-functional applications. At present, composite materials, super capacitors and corresponding personal care products based on carbon nanotubes are widely used in all aspects of people’s lives, and these products have obvious functional advantages. In this paper, based on the application of single-walled carbon nanotubes technology in personal care products, the separation and purification of ginsenoside pods, the raw material of high-end washing and care products, was studied. In order to enhance the conductivity and tensile strength of SWNTs, this paper innovatively introduces the purification method of current acid treatment to enhance the performance of SWNTs. Based on the improved single-walled carbon nanotubes technology, the extraction efficiency of the optimized single-walled carbon nanotubes was analyzed. In the end of this paper, the optimized extraction method of ginsenoside pods from SWNTs is compared with the traditional extraction method. The experimental results show that SWNTs has obvious time efficiency advantage.

AbstractCarbon nanotubes (CNT) are interesting candidates for the reinforcement in robust composites and for conducting fillers in polymers due to their fascinating electronic and mechanical properties. For the first time, we report the incorporation of multi walled carbon nanotubes (MWNTs) into silica-glass surfaces by means of partial surface-melting caused by a continuous wave Nd:YAG laser. MWNTs were detected being well incorporated in the silica-surface. The composites are characterized using scanning electron microscopy (SEM) and Raman-spectroscopy. A model for the composite-formation is proposed based on heatabsorption by MWNTs and a partial melting of the silica-surface.
