Abstract

Abstract

To solve the problem of food and medicine being easily contaminated by bacteria and its packaging causes environmental pollution problems, γ-aminopropyltriethoxysilane (KH-550) was used to modify the basic magnesium hypochlorite (BMH), and was compounded with polyvinyl alcohol (PVA) to obtain modified basic magnesium hypochlorite/polyvinyl alcohol composite membrane (modified BMH/PVA composite membrane). SEM, contact angle analysis, bacteriostatic zone experiment and FTIR have proved the effectiveness of organic modification of BMH. The antibacterial performance of modified BMH in PVA can be maintained by adjusting the pH value (The antibacterial rate is close to 100%). And when the content of organically modified BMH is 3wt%, the elongation at break of the modified BMH/PVA antibacterial composite film is increased by 25%, which not only makes the PVA film have antibacterial properties, but also improves its toughness. The conclusions indicate that the modified BMH/PVA antibacterial composite film is a promising antibacterial film material.
