Description

technical field [0001] The invention belongs to the technical field of nanomaterials, and in particular relates to a nanomaterial with the function of absorbing formaldehyde and a preparation method thereof. Background technique [0002] During interior decoration, organic gases such as formaldehyde will be volatilized indoors. People who work or live in such an environment for a long time will cause serious harm to their health. [0003] New materials represented by nanomaterials have broad application prospects in many fields because of their different properties from traditional materials. Through design, the selected nanoparticles or nanostructures are used as additive components to be compounded with the polymer material matrix, which will enhance and optimize the performance of the polymer material. [0004] However, the existing nanomaterials need to be improved in terms of purifying formaldehyde. If nanomaterials with the function of absorbing formaldehyde can be de...
