Chemistry is the experimental and theoretical study of materials on their properties at both the macroscopic and microscopic levels.In a patent， Safety of Tetrapropylammonium bromide, Which mentioned a new discovery about 1941-30-6
Effect of surfactants present in alkaline and acidic solutions on the capacitance of carbon electrodes has been studied. Three various types of surfactants, i.e. sodium dodecyl sulphate (SDS), tetrapropylammonium bromide (TPAB) and non-ionic such as polymer of polyethylene glycol and p-t-octylophenol (Triton X-100) have been selected for this target. Concentration of these electrolyte additives was 0.005 mol L-1. Decreasing the surface tension in the electrode/electrolyte interface allows better penetration of electrolyte into the pores. However, surfactants played a different role depending on the electrode polarity. Detailed analysis of capacitance versus current load, frequency dependence as well as self-discharge and cyclability proved especially a profitable effect of Triton X-100 on capacitor operating in alkaline solution.
I hope this article can help some friends in scientific research. I am very proud of our efforts over the past few months and hope to 1941-30-6, help many people in the next few years.COA of Formula: C12H28BrN
