▎ 摘　　要

NOVELTY - Coating composition comprises 0.1-0.5% graphene oxide nanoparticles, 10-30% globular protein, 7-17% plasticizer, 0.5-3% thickener, 5-20% filler, 0.5-2.9% fungicide and water. USE - The composition is useful for coating paper pulp renders it waterproof and completely biodegradable; and biodegradable bottle. ADVANTAGE - The composition: reducing single use plastic waste; protecting environment from plastic pollution; provides compostable ecofriendly alternative article to plastic bottles, bags and other articles; and provides solution that has the potential to replace all types of plastic packaging. DETAILED DESCRIPTION - INDEPENDENT CLAIMS are also included for: coated paper pulp comprising the coating composition comprises 0.1-0.5% graphene oxide nanoparticles, 10-30% globular protein, 7-17% plasticizer, 0.5-3% thickener, 5-20% filler, 0.5-2.9% fungicide and water; article comprising the coated paper pulp; preparing the coated paper pulp comprising preparing emulsion of 0.1-0.5% graphene oxide in water, and dextrin, or saccharide, and/or polysaccharide, adding of 10-30% globular protein, 7-17% plasticizer, 0.5-3% thickener, 5-20% filler, and 0.5-2.9% fungicide to form suspension, coating of paper pulp with the suspension, optionally removing excess suspension, thermal annealing at temperature of 180° C for 1-3 hours, and optionally drying of the coated paper pulp; and biodegradable bottle comprising the coating composition.
