Polymer containing amino-oxy structure, formaldehyde adsorbent and preparation method of formaldehyde adsorbent
2019
The invention belongs to the technical field of high molecular materials and harmful gas treatment, and particularly relates to a polymer containing an aminooxy structure, a formaldehyde adsorbent containing the polymer and a preparation method of the formaldehyde adsorbent. A polymer containing a large amount of aminoxy groups is obtained by utilizing reversible addition-fragmentation chain transfer (RAFT) polymerization or Atom Transfer Radical Polymerization (ATRP), and the polymer and a two-dimensional carrier material are loaded on porous melamine foam or polyurethane foam together to prepare the aerogel material, which is a three-dimensional material capable of efficiently adsorbing gas formaldehyde, namely a formaldehyde adsorbent. The formaldehyde adsorbent disclosed by the invention realizes reversible chemical adsorption on formaldehyde gas at normal temperature and normal pressure without the action of a catalyst, can be used for specifically and efficiently adsorbing gas formaldehyde by combining the high specific surface area of the carrier and the three-dimensional porous structure of foam, and can be used for desorbing formaldehyde under the action of dilute hydrochloric acid, so that the formaldehyde adsorbent can be repeatedly utilized.
