文章

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

Self-healing soft electronic materials offer potential cost savings and reduced electronic waste.

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

Professor Chen (Nankai University, China) and his team explain the strategies behind their recent record-breaking organic solar cells, reaching a power conversion efficiency of 17.3%.

Questions

  1. what is the density,molecular weight,and particle size.

    1 answer
    1. This product is supplied as an insoluble black solid. The material consists of approximately 80 percent carbon black, 20 percent polypyrrole, and a proprietary amount of an organic sulfonic acid dopant. The bulk density is not determined. Due to the high carbon black content, the compound is expected to be quite 'fluffy'. The molecular weight is also not determined. The average particle size is approximately 40 nm by Transmission Electron Microscopy (TEM) when fully dispersed. The powder form as provided is not dispersed and may form clumps or chunks.
