Abstract
A flame-retardant and abrasion-resistant composite is provided, and includes a nano-porous material and a polymer. The nano-porous material includes a plurality of powder having a particle size of less than 20 micrometers. A specific surface area of the powder is 50 to 3,000 m2/g. An amount of the powder is 50 parts per million to 30 wt %. The nano-porous material is dispersedly bound to the polymer and a limiting oxygen index of the composite is greater than or equal to 24%.
