Problems solved by technology

[0009] At present, the molecular membrane self-assembly method is an effective method that is beneficial to control the assembled structure and shape. The molecules of the self-assembled membrane are arranged in an orderly and compact manner, and the structure is regular, but the assembly process is complicated and requires high equipment requirements. better laboratory

Most of the generated membranes have poor stability to heat, chemical environment, time and external pressure. At the same time, the preparation of the membrane requires expensive membrane tanks and strict substrates. In addition to the substrate, the concentration of the solution, pH, cleaning and adsorption time, etc. will affect the assembly. quality
