Description

technical field [0001] The invention relates to the technical field of geogrids, in particular to an antibacterial and anti-oxidation geogrid and a preparation method thereof. Background technique [0002] As a typical one-dimensional nanomaterial, carbon nanotubes have a large aspect ratio, ultra-high elastic modulus and bending strength, unique electrical conductivity, excellent thermal conductivity, and strong acid resistance compared with traditional fillers. , strong alkali and other advantages. Studies have shown that by combining carbon nanotubes and polyolefins to fully combine their respective properties, a multifunctional polyolefin / carbon nanotube composite material with excellent mechanical, electrical conductivity, and flame-retardant properties can be prepared. The potential huge advantages of polyolefin / carbon nanotube composite materials have attracted extensive attention from researchers at home and abroad; [0003] Although compared with ordinary polymer ...
