polyaniline synthesized by means of condensation polymerization - Physico-chemical Properties
| Physical and Chemical Properties | Polyaniline with regular molecular chain was synthesized by Schiff route. Polyaniline with conductivity of 0.02-0.025 (S/cm) after doping. Comparing the optical, magnetic, electrochemical behavior and spectral data of the products, it is found that the polyaniline synthesized according to this route has the same properties as the polyaniline synthesized by ammonium persulfate and hydrochloric acid system. |
polyaniline synthesized by means of condensation polymerization - Introduction
Polyaniline is an important polymer, which is synthesized by Polycondensation Method. The following is an introduction to the nature, use, preparation and safety information of Polyaniline:
