Abstract

The invention relates to a polymer composite material with a rough surface, a nano carbon material, a preparation method and application. The preparation method comprises the following steps: mixing aphenolic compound, a carbonyl compound, an amino compound and a colloid template solution, performing sequential polymerization by utilizing dynamic difference of polycondensation reaction, Schiff base reaction and Mannich reaction on a micelle interface, and generating nano islands or nano particles on the surface or the edge of a nano material, thereby constructing a rough structure on the surface of the nano material. The method does not need additional etching and deposition processes, and the process is simple and controllable. The adsorbent prepared by the method can realize rapid diffusion of gas, and the diffusion rate is 5-10 times that of a commercial adsorbent; and by utilizing the catalyst carrier prepared by the invention, metal active particles can be anchored, migration andagglomeration of active components under a high-temperature condition are inhibited, and the stability of the catalyst is effectively improved.

Description

technical field [0001] The invention belongs to the field of nanometer materials, and in particular relates to a rough-surfaced polymer composite material, a nanocarbon material, a preparation method and an application. Background technique [0002] Adsorption separation technology is an important technology for separation and purification of mixed gases in industry. It has the characteristics of fast adsorption rate and high selectivity. It has the advantages of low energy consumption, low corrosion and high purity when used in the separation of mixed gases. Adsorbent is the core of adsorption separation technology, and the indicators for evaluating adsorbent mainly include adsorption capacity, selectivity and adsorption rate. Among them, the adsorption rate affects the energy consumption of the separation process. The faster the rate, the less energy consumption in the chemical production process. The development of adsorbents with fast adsorption rates is an important dem...
