Development and characterization of screen-printed Prosopis Africana Char thick film for electronic applications

The need for biomass materials that are both cost-effective and highly effective has increased rapidly in a number of areas, including flexible electronics. The aim of this research is to investigate the properties of a screen-printed thick film of Prosopis Africana charcoal (PAC) on an alumina substrate. The biochar was obtained from the Prosopis Africana strain by subjecting it to controlled pyrolysis at 500 °C for 3 h. The rheological properties of the PAC pastes were formulated at a powder-to-organic binder ratio of 40:60 wt
