▎ 摘　　要

NOVELTY - Silver/carbon nanotube (CNT)s/graphene oxide (GO) composite having sandwich interlayer structure comprises GO thin layer at top and bottom layers, CNT middle layer having a hollow structure and nano silver particles uniformly dispersed in GO and CNT. USE - The silver/CNTs/GO composite is useful for inhibiting bacteria (claimed), including Gram-positive bacteria (Staphylococcus aureus) and Gram-negative bacteria (Escherichia coli). ADVANTAGE - The method: is simple, easy, convenient, easy to control and environmentally friendly; and utilizes graphene and CNTs, which has synergistic immobilization capacity with nano-silver, thus increasing the stability of nanocomposite and improving the dispersion of nano-silver particles. DETAILED DESCRIPTION - An INDEPENDENT CLAIM is also included for preparation of silver/CNTs/GO composite, comprising (a) preparing dopamine hydrochloride solution, adding CNT and magnetically stirring at room temperature, (b) centrifuging, washing with distilled water, adding aqueous solution of GO and water and magnetically stirring at room temperature, (c) adding silver nitrate solution and sodium borohydride solution and stirring at room temperature and (d) centrifuging, washing with water and ethanol for 3 times and vacuum drying at room temperature for 24 hours.
