Yingtai: The Impact of Different Sterilization Methods on The Chemical Properties of Materials

Yingtai: The Impact of Different Sterilization Methods on the Chemical Properties of Materials

1. High-temperature sterilization method (such as steam sterilization)

Chemical property impact: Polymer materials: High temperatures can cause thermal degradation of polymer materials, altering their chemical structure, mechanical properties, and physical properties. Paper-plastic materials: Paper-plastic materials may lose their original physical properties at high temperatures, for example, paper may become brittle, and plastic parts may deform.

2. Chemical disinfection sterilization method (such as the use of ethanol, iodophor, peroxides, etc.)

Chemical property impact: Organic materials: Chemical disinfectants may react with organic materials, leading to changes in material properties, such as color, texture, or structural changes. Sensitive materials: Some chemical disinfectants are corrosive to sensitive materials and may damage their chemical properties.

3. Ultraviolet sterilization method

Chemical property impact: Polymer materials: Ultraviolet light may cause chain scission in polymer materials, altering the chemical properties of the materials. Sensitive materials: Ultraviolet light may cause photochemical reactions in some sensitive materials, thereby affecting their chemical properties.

4. Plasma sterilization method

Chemical property impact: Polymer materials: Plasma sterilization has a minimal impact on the chemical properties of materials but may cause certain chemical changes in sensitive materials. Inorganic materials: Plasma sterilization has a minimal impact on the chemical properties of inorganic materials but may alter the chemical composition on the material surface.

In summary, when selecting a sterilization method, it is essential to consider the potential impact of the sterilization method on the chemical properties of the materials. For example, for materials that require long-term storage, high-temperature sterilization methods that may cause changes in material properties should be avoided. For sensitive materials, sterilization methods with minimal impact on the chemical properties of the materials, such as plasma sterilization, should be chosen. At the same time, for certain specific-use materials, such as medical non-woven fabrics or paper-plastic packaging materials, special attention needs to be paid to their stability under different sterilization methods to ensure the effectiveness of sterilization and the long-term effectiveness of the materials.
