Ultra-efficient membrane separation technologies are needed to reduce the cost of mol. separations However, the two-dimensional isotropy of conventional selective membrane limits the freedom for deep optimization of separation process. In addition, the membrane separation properties, e.g. permeability, are difficult to be accurately pre-determined according to actual needs of applications, because membrane fabrication is largely empirical and lacks highly-controllable structure variable. Herein, we develop a novel thin-film composite membrane with high controllability, where two kinds of polyamides differing in structural and physicochem. properties are integrated into a unity according to pre-designed proportion and distribution, by generating heterogeneous polymerization interface with the help of inkjet printing. The separation performance of the heterostructure (HS) membranes show function relationships with the fabrication parameters (the essence is the ratio of different structures). The separation properties of every point (micron scale) of membrane can be individually managed. Thus, the HS design not only enables programmable, pre-determined membrane separation properties, but also opens the door to controlling their spatial distribution within membrane plane. Furthermore, the membrane with gradient permeability is proposed to solve the problem of flux imbalance within membrane elements, showing the great potential of the HS design in ultra-efficient membrane separation process. In the experiment, the researchers used many compounds, for example, Trimesoylchloride (cas: 4422-95-1Recommanded Product: 4422-95-1).
Trimesoylchloride (cas: 4422-95-1) belongs to organic chlorides. An organic chloride is an organic compound containing at least one covalently bonded atom of chlorine. Their wide structural variety and divergent chemical properties lead to a broad range of names and applications. Alkanes and aryl alkanes may be chlorinated under free radical conditions, with UV light. However, the extent of chlorination is difficult to control.Recommanded Product: 4422-95-1
