Abstract

The invention relates to a composite material for selectively reducing aldehyde material in smoke of a cigarette. A porous material serves as a carrier of the composite material. Polyelectrolyte nano particles are loaded on the surface of the carrier. Each polyelectrolyte nano particle is a complex of cationoid polyelectrolyte and anionic polyelectrolyte. The mass percentage composition of the polyelectrolyte nano particles in the composite material is 0.01-10.0%. The cationoid polyelectrolyte is one or more of poly-dimethyl-diallyl-ammonium chloride, poly(2-trimethylammoniumethyl methacrylate chloride), polylysine hydrochloride, amino polyethylene glycol hydrochloride, double amino polyethylene glycol hydrochloride and polyacrylamide. The anionic polyelectrolyte is one or more of polyaspartic acid sodium, sodium polyacrylate, carboxyl polyethylene glycol, double carboxyl polyethylene glycol, sodium polystyrene sulfonate and sodium humate. The preparation process of the composite material is simple, adopted raw materials are convenient and easy to obtain, price is low, and the composite material has good industrial applicability.

Description

technical field [0001] The invention relates to the technical field of cigarette harm reduction, in particular to a composite material for selectively reducing aldehydes in cigarette smoke, a preparation method and application thereof. Background technique [0002] Cigarette smoke contains a variety of aldehyde compounds, among which low-molecular-weight aldehydes are mostly harmful substances, especially several low-molecular-weight aldehydes including formaldehyde, acetaldehyde, acrolein, propionaldehyde, crotonaldehyde, and butyraldehyde. Formaldehyde, acrolein and crotonaldehyde are toxins in the cilia of the respiratory tract, which can cause lung diseases and damage the health of the body. Therefore, selectively reducing formaldehyde, acrolein, crotonaldehyde and other low-molecular-weight aldehydes in cigarette smoke can reduce the toxicity of smoke to respiratory cilia, thereby reducing the harm of cigarettes. [0003] At present, there have been some reports on how...
