Description générale

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.

Application

Conducting polymers may be used in electronics, chemical sensors.
PPy can be used in the development of devices including:
  • conductive sensors for quality monitoring
  • blended with nanotubes for supercapacitors
  • nanowire actuators
  • biosensors for drug delivery
  • CO2 absorption materials

Conducting Polymer Device Applications

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

Stretchable Electroluminescent Devices

Dr. Tan and researcher introduce recent trends in Self-healing Soft Electronic Materials and Devices. The emergence of smart, functional SHPs will be highly beneficial to the advancement of the next-generation self-healing soft electronic devices. Autonomously self-healing devices could help to minimize the need for repair or replacement of electronics and machines, potentially reducing the cost of materials and reducing electronic waste.

Understanding and Successfully Applying Materials for Dye-Sensitized Solar Cells

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/cm

Recent Advances in Hybrid Halide Perovskites-based Solar Cells

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.
