How to choose membrane materials suitable for specific applications?

Clarify Application Scenarios and Core Requirements

Classification of Application Scenarios

• Healthcare (e.g., medical warming blankets): Focus on biocompatibility, antibacterial properties, breathability, temperature resistance, and sterilization compatibility.
• Industrial (e.g., filtration membranes): Prioritize chemical resistance, mechanical strength, pore size control, and anti-fouling properties.
• Food Packaging: Emphasize barrier properties (against oxygen and water vapor), safety (non-toxic and non-migratory), and transparency.
• Electronics (e.g., battery separators): Require ionic conductivity, thermal stability, and electrochemical stability.

Core Requirement Priorities

• Functional needs: Such as breathability, barrier properties, conductivity, or antibacterial performance.
• Environmental adaptability: Including resistance to high/low temperatures, acids/alkalis, and UV exposure.
• Safety and compliance: For example, medical-grade materials must comply with ISO 10993, while food-grade materials must meet FDA standards.
