Comprehensive Enhancement of Mechanical, Water-Repellent and Antimicrobial Properties of Regenerated Seaweed and Plant-Based Paper with Chitosan Coating

Regenerated papers made from discarded natural sources, such as seaweeds or non-wood plants, are viewed promising eco-friendly alternatives relative to conventional wood-based paper. However, due its limited mechanical strength and higher water absorption than compared traditional wood paper, it often results in premature structural disintegration. In order overcome this limitation, research introduces an efficient comprehensive strategy of coating seaweed plant with varying concentrations molecular weights chitosan. Increased concentration weight resulted a greater amount chitosan deposition, while the highest also shows increased dissolution soluble components Since plants contain high anionic polysaccharide contents, cationic binding affinity towards The resulting chitosan-coated demonstrate significant enhancements repellency properties. addition, show bacterial inhibition effects anti-microbial activity
