Traditional cellulose wrapping paper existing many problems, such as poor barrier, easy water absorption, etc. Herein, cellulose, polylactic acid non-woven fabric and antibacterial short fiber as raw materials, via wet papermaking process, prepared a biodegradable and antibacterial composite paper (SP/CFPLA-6%). Compared with the traditional cellulose paper, the water vapor transmittance of SP/CFPLA-6% decreased by 84.2%, showing obvious hydrophobicity. The tensile strength of SP/CFPLA-6% can reach 95.8 MPa, which is more than 70 MPa higher than that of ordinary cellulose paper, displaying promising antibacterial activity against Escherichia coli and Staphylococcus aureus . Meanwhile, SP/CFPLA-6% shows excellent biodegradability in biodegradation experiments. SP/CFPLA-6% offsets the shortcomings of ordinary cellulose wrapping paper and can be used as a substitute for traditional non-degradable plastic packaging materials.

We report a simple method to synthesize spherical and irregular sodium lignosulfonate (SLS)-stabilized zinc oxide (ZnO) nanoparticles using water as a solvent, SLS as a stabilizing agent, and sodium hydroxide as a precipitation agent. The presence of SLS on the surface of ZnO nanoparticles can improve the dispersion of the nanoparticles and make them negatively charged. The negatively charged SLS-stabilized ZnO nanoparticles can be deposited onto cellulose paper through a layer-by-layer (LBL) approach. The resultant cellulose paper samples, coated with ZnO nanoparticles, show good antibacterial activity against both Gram-positive Bacillus subtilis and Gram-negative Escherichia coli.

Although silver nanoparticles (AgNPs) have the effective antibacterial property, its application was limited by the accumulated toxicity. It was necessary to develop a carrier material to immobilize AgNPs. In this study, for the first time, thiol-modified carbon spheres (TMCS) were synthesized by hydrothermal method, which was used to immobilize AgNPs. It effectively solved the problem of cumulative toxicity. Thiol-modified carbon spheres loaded with silver nanoparticles (TMCS@Ag) were then blended with pulp fibers to prepare antimicrobial composite paper. The addition of TMCS@Ag changes the internal microstructure of the paper, improves its mechanical properties and thermal stability, and at the same time reduces solubility and swelling, which is conducive to use and preservation. It is worth noting that due to the immobilization of TMCS and the wrapping effect of paper fibers, the cumulative release of Ag + in the composite paper reached only 5.15 % on the 14th day, and the cell survival rate was >95 % after co-culture, which proves that the release rate was controlled and the cumulative toxicity of AgNPs was effectively reduced. Nevertheless, the composite paper still has good antimicrobial properties against E. coli and S. aureus . Therefore, this study provides a new strategy for the safe application of antibacterial paper in food preservation, medical and health fields.

Hydroxyapatite is a kind of biocompatible, environmentally friendly, and versatile inorganic biomaterial. Herein, the preparation of ultralong hydroxyapatite nanowires (HAPNWs)-based antibacterial paper co-loaded with silver nanoparticles (AgNPs) and antibiotic is reported. HAPNWs are used to prepare AgNPs in situ using an aqueous solution containing AgNO3 under the sunlight without added reducing agent at room temperature. Subsequently, ciprofloxacin (CIP) as an antibiotic is loaded on the HAPNWs@AgNPs. The resultant HAPNWs@AgNPs-CIP paper possesses several unique properties, including high flexibility, high Brunauer–Emmett–Teller (BET) specific surface area (47.9 m2 g–1), high drug loading capacity (447.4 mg g–1), good biocompatibility, sustained and pH-responsive drug release behavior (5.40–6.75% of Ag+ ions and 37.7–76.4% of CIP molecules at pH values of 7.4–4.5 at day 8, respectively), and reusable recycling. In the antibacterial tests against Escherichia coli and Staphylococcus aureus, the HAPNWs@AgNPs-CIP paper exhibits large diameters of inhibition zones and low minimum inhibitory concentrations (30 and 40 μg mL–1), revealing the high antibacterial activity. Besides, the consecutive agar diffusion tests (8 cycles), long-term stability tests (over 56 days), and continuous contamination tests (5 cycles) demonstrate the excellent recycling performance and long-term antibacterial activity of the HAPNWs@AgNPs-CIP paper. These results indicate a promising potential of the HAPNWs@AgNPs-CIP bactericidal paper for tackling public health issues related to bacterial infections.

We prepared tea tree essential oil microcapsules, and the microcapsules and pullulan were coated on kraft paper to prepare an antibacterial paper. The antibacterial activity, structural characterization, and thermal stability of the prepared microcapsules and packaging paper were then tested. We found that the retention rate of microcapsules reached 87.1% after a 70 min of high-temperature treatment. The minimum inhibitory concentrations of microcapsules to S. aureus and E. coli were 112 mg/mL and 224 mg/mL, and the bacteriostatic zones of the packaging paper to E. coli and S. aureus were 17.49 mm and 22.75 mm, respectively. The prepared microcapsules were irregular. The paper coating was formed via hydrogen bonding, which filled the pores of paper fibers. When compared with the base paper, the roughness of the paper was reduced to 7.16 nm (Rq) and 5.61 nm (Ra), and no thermal decomposition occurred at <288 °C, which together implies a good application prospect.
