resumo
Waste swamps, stagnant water, and poor hygiene practices result in the proliferation of mosquitoes that may cause transmissible and infectious diseases such as malaria, typhoid, cholera, and Zika virus sickness. It has been shown that composites of the traditional natural fibers cotton, viscose, and linen and a Ti-bearing metal-organic framework, NH2-MIL-125, are very effective against mosquitoes in the absence of any conventional insecticides. In our study, prior to coating with NH2-MIL-125 crystals, the fabrics were modified with 3-glycidyloxypropyltrimethoxysilane. The composite materials were characterized by powder X-ray diffraction, UV-vis spectroscopy, Fourier transform infrared spectroscopy, and scanning electron microscopy with energy-dispersive X-ray spectroscopy analysis. The latter, in particular, has shown the uniform coating of the fabrics with NH2-MIL-125 crystals. The modified fabrics have excellent antimosquito properties, attracting and killing them.
