Conducting polymer membrane from Coal by Dr Atma Ram Singh

For the first time, an additive for a conducting polymer membrane has been successfully developed from Indian coal—a breakthrough deeply inspired by my father’s pioneering research in coal chemistry and structural modeling. Using Samla coal from the Raniganj coalfield (80% carbon, dmmf basis), the coal was chemically demineralised, oxidized, and solubilized in a polar organic solvent. The soluble fraction was dried, and the residual solid was blended with polyvinyl alcohol to create an additive for conducting polymer membranes, forming a high-quality, coloured thin film with conductivity in the range of 10⁻³–10⁻⁴ Scm⁻¹.

Building upon my father’s insightful observations and the Mazumdar model of coal structure, this study addresses a long-standing anomaly regarding the enhancement of carboxylic acid functional groups (from 1.2% to 18.3% upon oxidation) and proposes a correction to better explain these experimental results—further extending his legacy in coal structure analysis and functional group chemistry.
