Effect of antibacterial and compatibilizer agents on properties of low-density polyethylene composites

In this study, antibacterial low-density polyethylene (LDPE) composites were prepared using a silver-based antibacterial agent (Ag agent) and compatibilizer (linear low-density polyethylene-g-maleic anhydride (LLDPE-g-MA)), and their thermal, mechanical, and antibacterial properties were examined. The crystallization temperatures of the compatibilizer/antibacterial composites were higher than those of the composites prepared without a compatibilizer. LDPE is a crystalline material, and the addition of LLDPE-g-MA reduced the PE content and enthalpy of the composite and improved the dispersibility of the Ag agent between the substrates. The antibacterial activity test revealed that the addition of the Ag agent and compatibilizer to LDPE composites enhanced their antibacterial effects.
