Biological studies and electrical conductivity of paper sheet based on PANI/PS/Ag-NPs nanocomposite

•Conductive paper sheets with good electrical & mechanical properties were prepared.•Ag-NPs was used to enhance the antibacterial properties of the prepared paper sheet.•The prepared paper sheets were studied using SEM, XRD and IR.•Some biological studies were evaluated for the prepared paper sheets.•The prepared paper sheet can be used as packaging materials.

Polyaniline (PANI) with/without polystyrene (PS), was successfully manufactured in the occurrence of dispersed pulp fibers via the oxidative polymerization reaction of aniline monomer to produce conductive paper sheets containing PANI, PANI/PS composites. Additionally, sliver nitrate (Ag-NO3) was added by varied loadings to the oxidative polymerization of aniline monomer to provide sliver nanoparticles (Ag-NPs) emptied into the prepared paper sheets. The prepared paper sheets were examined using scanning electron microscopy (SEM), X-ray diffraction (XRD) and infrared spectroscopy (IR), the mechanical properties of the prepared paper sheets were evaluated. Moreover, the electrical conductivity and biological studies such as cellulases assay, Microorganism & culture condition and detection of the released of Ag-NPs were evaluated. Furthermore, the prepared paper sheets were displayed good antibacterial properties contrary to gram positive and gram negative bacteria. Consequently, the prepared paper sheet may be used as novel materials for packaging applications.
