Design, Preparation and Gas Separation Performance of the Functional Carbon Membranes;

Gas permeation test results show that all the functional carbon membranes exhibite an outstanding molecular sieving capability together with high gas permeability,especially to micromolecule gas H2 whose permeability is increased by 48 times at most.

The paper first gives a brief introduction to the concept of nanometer, nanostructure, nano-functional films, etc.

Titanium dioxide photocatalytic thin film is a kind of functional film to which many attentions are paid by many researchers at present.

TiO2 functional film was prepared through solgel process.

The classification, variety and characteristics of functional thin films were stated in this paper.

In this paper, we introduce briefly the principle,the characteristics and the advantages of this technique and review its intensive applications in the study of functional thin films.

Many functional thin films are involved in the structure of TEFL device, and the properties of TFEL device are attributed to the materials and the fabrication methods of functional films.

Solid phase transmission photometric determination of palladium with PVC functional membrane was studied.

Solid phase reflection spectrophotometric determination of Cd(Ⅱ) with PVC functional membrane was studied.

To the chip integrated with pH-ISFET,fabricating excellent pH functional membrane with MEMS processes is the key factors in development.
