Abstract: • Green porous, biocompatible and sustainable composite bases on natural materials. • Dielectric study reveals the enhanced composite having antistatic charge property. • The composite conductivity range is10−9–10−6 S/cm. • Zeta potential shows excellent colloidal stability and easily-use in applications. New approach for composite material (NMC) based on nicotinic acid (NA) and methyl cellulose (MC) is reported. This kind of material has pros as nontoxic, biocompatible, renewable from available raw materials. The preparation and characterizations of the composite were made using Fourier-transform infrared (FTIR), scanning electron microscope (SEM), Thermo gravimetric analyses (TGA and DTA) and Zeta potential. The dielectric broadband spectroscopy studies for dielectric relaxation and conductivity properties are investigated and determined. The FTIR has confirmed the diffusion reaction of nicotinic acid with methyl cellulose forming the antistatic charge composite with good thermal stability up to 250 °C. The dielectric relaxations reveal enhancement to the methyl cellulose to be antistatic charges material with conductivity range 10−9–10−6 S/cm. The Zeta potential result −66 mV shows excellent stability for colloidal composite which promises easier ways in application as spray paint on surfaces that is accumulating static charge.
