Nano noble metal particles coated container made from porous material, and preparation method

Abstract

An antibacterial and antiaseptic container with catalytic effect and coated noble metal nanoparticle film is prepared from a raw container made of porous material, adding the noble metal nanoparticles and medium particles to the aqueous solution at the first temp, baking said container to the second temp higher than the first temp, immersing it in said aqueous solution to make said nanoparticles and particles penetrate in the surface of container, baking it to the third temp, and sintering.

Description

technical field [0001] The invention provides a porous material container and a preparation method thereof, especially a method that allows nano-media particles and nano-precious metal particles to permeate and sinter on the surface of the porous material container and the small pores densely distributed thereon, The invention relates to a method for preparing a container with a precious metal film, and the container prepared by the method has long-term antibacterial, anti-corrosion and catalytic effects. Background technique [0002] A nanometer is a unit of length, 1 nanometer equals one billionth of a meter (10 -9 meter), which is about the size of a molecule or DNA, or one hundred thousandth of the width of a hair. , the classical theory does not seem to be applicable to the materials formed by nanoparticles, on the contrary, the quantum effect (quantum effect) has become a characteristic that cannot be ignored. In addition, due to the high surface / volume ratio, high de...

Problems solved by technology

However, in fact, it can be easily known from traditional methods that due to the effect of the surface tension of the solution, the nanoscale noble metal particles cannot penetrate into the densely distributed small pores on the surface of the porous material container, and only adhere to the surface of the container. After drying, although a nano-precious metal particle film is formed on the surface of the container, the film is easily peeled off due to friction after being used and cleaned several times, and loses its proper antibacterial, antiseptic, deodorizing and catalytic functions. , how to design a porous material container, so that nano-precious metal particles have to infiltrate the surface of the porous material container and the small pores densely distributed on it, and be sintered on the surface of the container and the small pores on it, so that the formed Nano precious metal film has long-term antibacterial, anti-corrosion and catalytic effects, which has become an important issue that needs to be solved urgently in the industry
