Abstract

The invention discloses nano-carbon sol and application thereof; the nano-carbon sol is characterized in that the carbon particle size is in the range from 1 to 500 nm; the nano-carbon sol is prepared by adding sodium lignin sulfonate, which is 0.08-0.12% of the total weight of sol and is 6500 Dalton in molecular weight, into the nano-carbon sol obtained by electrolyzing water by taking a graphite electrode as the anode; the carbon content in the sol is 0.6 wt%. The nano-carbon sol disclosed by the invention is applied to petrochemical industries, medicines, environmental protection, antiviral protection and catalysts; in the aspect of medicines, the nano-carbon sol can be used as a medicine additive and a film wrapped for external injury; in the aspect of petrochemical industries, the nano-carbon sol can be used as a dispersing agent in the refining process; in the aspect of environmental protection, the nano-carbon sol can be used as a flocculating agent and bactericide for water treatment; in the aspect of antiviral protection, the nano-carbon sol not only can be used as an antiviral filtering material but also can be used as a chemical catalyst; the nano-carbon sol disclosed by the invention has the antiinflammation effect; a nano-carbon sol medical catheter has excellent mechanical strength, good low-friction of the sliding surface and antithrombus; in addition, the nano-carbon sol disclosed by the invention has excellent biological degradability.

Description

technical field [0001] The invention belongs to the technical field of medical application and medical supplies, and in particular relates to a nanometer carbon sol and its application. Background technique [0002] In clinical medical treatment, it is necessary to use medical lines in the respiratory tract, trachea, digestive tract, urethra, blood vessels or other abdominal cavity or tissues, such as tube endoscopes, guide sheaths and other catheters or medical supplies inserted, which must have Considerable smoothness, so that human tissue can not be damaged when inserted, and membrane damage or inflammatory reaction caused by friction can be avoided, and operability can be improved. At the same time, these catheters are also required to have high mechanical strength to prevent catheter rupture during medical operations. However, the friction and mechanical strength of the medical catheters in the prior art often cannot meet the requirements, which can easily cause inflam...
