Abstract (English):
The study of radiation resistance of polypropylene is important for its use in medical devices. Polypropylene is often sterilized using ionizing radiation, which can lead to its degradation and a decrease in mechanical properties. This can negatively affect the safety and effectiveness of medical devices, such as surgical instruments and packaging for sterile materials. Therefore, it is important to select additives that can increase radiation resistance and ensure the reliability of polymers. In addition, it is necessary to conduct comprehensive tests to assess the durability and stability of polymers. This includes a study of the effect of temperature, humidity and other factors on the effectiveness of additives. It is important to note that an integrated approach to the selection of additives not only preserves the physical and mechanical properties of polypropylene, but also increases its reliability under sterilization conditions of medical devices. The article discusses the classification of additives for increasing the radiation resistance of polypropylene, divided by the mechanism of action: antioxidants, stabilizers, nanomaterials, compatibilizers and synergists. In the process of literature analysis it was revealed that nanomaterials and synergists have not yet been fully studied. It should be noted that the combined use of various additives such as stabilizers and antioxidants can significantly improve the radiation resistance of polypropylene. Stabilizers slow down oxidation processes, and antioxidants prevent the formation of free radicals, which is critical for the durability of materials. Further research in the field of synergists and nanomaterials for polypropylene can lead to the creation of more effective and safe materials for medical use. This will not only improve the quality of medical products, but also expand their functionality. The study of radiation resistance and the correct choice of additives are key factors in ensuring patient safety and increasing the effectiveness of treatment.
