Polyaniline Nanofiber

Abstract Among nano polyaniline materials, polyaniline nanofibers are the most important. The low conductivity and poor processability have become the biggest obstacles to the application of polyaniline as a practical material. The excellent characteristics of new polyaniline nanofiber materials can just overcome the shortcomings of Polyaniline in forming and processing. In this study, a new polyaniline nanofiber was prepared by chemical oxidation, its structure was characterized, the mechanism of improving its conductivity was studied, and its superior electrocatalytic activity was evaluated by Electrochemical performance test. The results show that the diameter of polyaniline nanofibers is 20nm ~ 50nm and the fiber length is 2µm ~ 5µm. The structure is uniform and the conductivity can reach 13.5 S/cm. he electrocatalytic activity of polyaniline nanofibers for oxygen evolution and chlorine evolution was systematically tested. It was found that the electrocatalytic activity of polyaniline nanofibers for oxygen evolution was higher than that of polyaniline nanofibers. The electrocatalytic activity of carbon paper electrode prepared by β-PbO2 nano powder is superior to that of traditional chlorine evolution anode Ti/RuO2.

And Function

Integrin β4 (ITGβ4) is a class of transmembrane adhesion molecules composed of hemidesmosomes (HDs). Its unique long intracellular domain provides intricate signal transduction functions. These signal transduction effects are especially prominent in tumors. Many recent studies have shown that integrin β4 is differentially expressed in various tumors, and it plays a vital role in tumor invasion, proliferation, epithelial–mesenchymal transition, and angiogenesis. Therefore, we categorize the research related to integrin β4, starting from its structure and function in tumor tissues, and provide a basic description. Based on its structure and function, we believe that integrin β4 can be used as a tumor marker. In clinical practice, it is described as a diagnostic marker for the targeted treatment of cancer and will be helpful in the clinical diagnosis and treatment of tumors.
