AI Technical Summary
Existing polypropylene cast films suffer from problems such as poor dispersibility, antibacterial agent migration, insufficient interfacial bonding, and limited heat resistance in terms of temperature resistance and antibacterial properties. They are difficult to maintain stable antibacterial effects in high-temperature environments, and existing technologies lack synergistic design, resulting in uneven performance and safety hazards.
By employing a supported antibacterial composite material and a crystallization control system, antibacterial active components are loaded and modified onto a porous carrier. Combined with a β-crystal nucleating agent to regulate the crystal structure, a stable interfacial synergistic structure is formed, which controls the release and dispersion of antibacterial components and improves the antibacterial durability and heat resistance under high temperature conditions.
Stable dispersion of antibacterial components in polypropylene matrix was achieved, avoiding migration and precipitation, maintaining long-term antibacterial effect, improving the mechanical properties and dimensional stability of the material, and achieving synergistic optimization of temperature resistance and antibacterial properties.
