Abstract

The invention discloses a preparation method of PET / PTT alloy capable of purifying air. A used antibacterial compound uses graphene quantum dots obtained after laser irradiation as carriers of antibacterial agents, surface treatment is carried out, and attachment to porous graphene is finally carried out, so that silver nanoparticles and other antimicrobial agents can better loaded and fixed, agglomeration thereof is prevented, the stability of the antimicrobial agents is significantly improved, and thus the PET / PTT alloy has more long-lasting antibacterial activity; meanwhile, diatomaceous earth can adsorb harmful gases in air, especially formaldehyde, so that the PET / PTT alloy also has an air purifying effect besides an antibacterial effect. Through reasonable collocation of a diatomite / antimicrobial composite material and diatomite / porous carbon and under a synergistic action of functional additives, the alloy has excellent antibacterial and formaldehyde-resistant characteristics, multifunctional needs are met, and thus the application of the PET / PTT alloy capable of purifying air is further widened.
