Descrizione generale

Polypyrrole (PPy) is a conductive and highly stable polymer, doped with proprietary organic acids. It may be prepared by standard electrochemical technique. PPy may also be prepared by reacting β-napthalene sulfonic acid (NSA) and ammonium peroxo-disulphate in aqueous medium. The charges on the surfaces can be easily modified by doping the polymer during its synthesis.Solubility and conductivity measurements of PPy doped with camphor sulfonic and dodecyl benzene sulfonic acid has been reported.
Polypyrrole(PPy) is a π-conjugated conductive polymer that can be electrochemically synthesized and deposited on a variety of surfaces. The deposited PPy can be used in a wide range of sensor based applications due to the following properties:
  • Ion exchange capacity.
  • Electrochromic effects.
  • Redox activity.
  • Corrosion resistant.
  • Catalytic activity.

We are committed to bringing you Greener Alternative Products, which adhere to one or more of the 12 Principles of Green Chemistry. This product enables flexible high-performance energy conversion and storage and thus has been enhanced for energy efficiency. Click here for more information.

Articoli

The application of conducting polymers at the interface with biology is an exciting new trend in organic electronics research.

While dye sensitization as the basis for color photography has been accepted for a very long time,1 attempts to use this principle for the conversion of solar light to electricity generally had resulted only in very low photocurrents, below 100 nA/cm2.2

For several decades, the need for an environmentally sustainable and commercially viable source of energy has driven extensive research aimed at achieving high efficiency power generation systems that can be manufactured at low cost.

Il team dei nostri ricercatori vanta grande esperienza in tutte le aree della ricerca quali Life Science, scienza dei materiali, sintesi chimica, cromatografia, discipline analitiche, ecc..
