An atmospheric plasma treatment strategy was developed to prepare two-dimensional (2D) molybdenum disulfide (MoS) and graphitic carbon nitride (g-CN) nanosheets from (NH)MoS and bulk g-CN, respectively. The moderate temperature of plasma is beneficial for exfoliating bulk materials to thinner nanosheets. The thicknesses of as-prepared MoS and g-CN nanosheets are 2-3 nm and 1.

In this paper, the advance of polymeric materials applied in the development of traditional Chinese medicine (TCM) and natural products was reviewed. Especially the research progresses in use of the polymeric membranes, polymeric flocculating agents, polymeric sorbents and polymeric drug delivery system (DDS) in the separation and preparation of herb and TCM were discussed in details. In addition, the future develorment of polymeric materials in TCM preparation was also discussed.
