Polyvinylidene difluoride

Manufactured by Solvay
Sourced in Japan

Polyvinylidene difluoride (PVDF) is a synthetic fluoropolymer material used in various laboratory equipment applications. It is a thermoplastic polymer with a high resistance to chemicals, solvents, and heat. PVDF exhibits strong mechanical properties and is suitable for use in a variety of laboratory equipment, such as beakers, bottles, tubing, and other components that require these material characteristics.

Fabrication of Supercapacitor Electrode

Check if the same lab product or an alternative is used in the 5 most similar protocols
NPC (80 wt.%) was mixed with carbon nanotubes (Sigma, Kawasaki, Kanagawa Prefecture, Japan; 10 wt.%) and polyvinylidenedifluoride (Solvay, Brussels, Belgium; 10 wt.%), and the electrode (d: 1 cm) was prepared by pressing the mixture at 10 MPa. A two-electrode system was used with active materials mass of 2 mg. The cyclic voltammetry (CV), galvanostatic charging/discharging (GCD), and electrochemical impedance spectroscopy (EIS) tests were performed on the EC-LAB VMP3 workstation (BioLogic Science Instruments, Seyssinet-Pariset, France), with 1 M Li2SO4 aqueous solution.

About PubCompare

Our mission is to provide scientists with the largest repository of trustworthy protocols and intelligent analytical tools, thereby offering them extensive information to design robust protocols aimed at minimizing the risk of failures.

We believe that the most crucial aspect is to grant scientists access to a wide range of reliable sources and new useful tools that surpass human capabilities.

However, we trust in allowing scientists to determine how to construct their own protocols based on this information, as they are the experts in their field.
