Chitosan-based nanofragrance with antibacterial function applied to wallpaper

Area of Science:

• Materials Science
• Biomaterials Engineering
• Chemical Engineering

Background:

• Fragrances enhance living and office environments but face challenges with wallpaper adhesion and rapid release.
• Current methods for incorporating fragrances into wallpapers are limited by poor retention and quick dissipation.

Purpose of the Study:

• To develop a novel method for incorporating fragrances into wallpapers with improved adhesion and controlled release.
• To enhance the functionality of wallpapers by imparting antibacterial properties.

Main Methods:

• Vanillin, a fragrance compound, was encapsulated within particles composed of chitosan and poly(lactic-co-glycolic acid).
• The fragrance-loaded particles were integrated into wallpaper formulations.
• Adhesion, release kinetics, and antibacterial activity were evaluated.

Main Results:

• The encapsulation of vanillin in chitosan and poly(lactic-co-glycolic acid) particles resulted in a slow-release fragrance system.
• The incorporation of chitosan significantly improved the adhesion of the fragrance to the wallpaper.
• The modified wallpaper exhibited notable antibacterial properties.

Conclusions:

• Encapsulating vanillin in chitosan and poly(lactic-co-glycolic acid) particles offers a viable solution for slow-release fragrances on wallpapers.
• This approach enhances fragrance longevity and adhesion while conferring antibacterial benefits to the wallpaper.
• The developed technology has potential applications in optimizing indoor environments through functionalized wallpapers.
