Graphene-containing latex. The latex contains a graphene structure and non-carbon, non-oxygen and non-hydrogen elements. The provided latex is enabled to have multiple performances such as far-infrared performance, antibacterial performance and bacteriostasis by selecting a specific carbon nanostructure compound and by means of collocation and combination of a graphene structure and elements such as Fe, Si and Al; and furthermore, higher far-infrared effect and antibacterial effect can be achieved by controlling a specific addition proportion. The experimental results prove that the far-infrared performance of the latex can reach a maximum value of 0.93, and the bacteriostasis can reach a maximum value of 99%.
