Abstract:
In this study, we have used hydroxyethyl cellulose (HEC) to prepare antimicrobial films for multipurpose applications. Using HEC gives mangiferin powder (M) mechanical properties, while mangiferin powder gives HEC antimicrobial activities. Various concentrations of M (2.5, 5 and 10% wt/vol) were added to HEC to enhance the antimicrobial ability of HEC/M films. The results showed that 10% (wt/vol) was the optimum concentration to accomplish the antimicrobial activity. Various analyses were performed to study the prepared films' physical, chemical, mechanical, and antimicrobial properties.
Insights
Hydroxyethyl cellulose (HEC) films incorporated with mangiferin powder exhibit enhanced antimicrobial properties. The optimal concentration of 10% mangiferin powder significantly boosts the antimicrobial activity of HEC films for versatile applications.
