A multifunctional paper-based composite of paper coated with a polypyrrole@lignocellulosic slurry (PPy@LS) and carboxymethyl cellulose (CMC) was developed. PPy@LS prepared via the polymerization pyrrole onto lignocellulosic derived from hemp stalks using deep eutectic solvents. The mixed required amount CMC vacuum-filtered filter to fabricate (PPy@LS/CMC). resulting exhibited excellent properties, including electrical conductivity, photothermal conversion, antibacterial properties. These properties are stable against external environments, such as water abrasion, due addition CMC. conductivity PPy@LS/CMC varied in dry (1.6 × 10-4 S/cm) wet (4.8 10-6 states, suggesting its potential application humidity sensing. Notably, achieved significant activity under light irradiation, demonstrated by measured surface temperature exceeding 80 °C 10 min. Moreover, > 99.9% Escherichia coli (Gram-negative) Staphylococcus aureus (Gram-positive). combination inherent characteristics along property PPy enable appropriate for solar interfacial evaporation application. papers innovative combinations have great applications smart packaging, sensing, biomedicine, solar-driven purifications.
