Description

Technical Field

[0001] This invention belongs to the field of chemistry, specifically relating to a fluorinated silicone-modified polycaprolactone material that can be directly thermally polymerized, its preparation method, and its application. Background Technology

[0002] Polycaprolactone (PCL), a biodegradable aliphatic polyester, possesses excellent biocompatibility and processing properties, making it a promising candidate for applications in environmentally friendly agricultural films and packaging materials. However, the inherent biodegradability of PCL becomes a significant drawback in certain applications requiring long-term stability, such as the encapsulation and substrates for flexible electronic devices. Its dielectric properties also struggle to meet the stringent requirements of low dielectric constant and low dielectric loss in high-frequency electronic devices, severely limiting the application of PCL in high-value-added fields such as the electronics industry.

[0003] To overcome the aforementioned limitations of PCL, modifying it to improve its overall performance is of significant practical importance. Introducing fluorine- or silicon-containing functional groups is an effective strategy for enhancing the polymer's hydrophobicity, thermal stability, and dielectric properties. In particular, perfluorocyclobutyl aryl ether (PFCB) structural units have become star structures in the design of high-performance polymer materials due to their ability to impart extremely low water absorption, excellent dielectric properties, high thermal stability, and good solubility. Introducing the PFCB structure into the PCL framework is considered an ideal approach to preparing materials that combine processability with superior dielectric properties.

[0004] Currently, there are existing technologies attempting to prepare fluorine-silicon modified PCL materials. For example, the method reported in Chinese patent CN 118184899 A typically requires introducing multiple fluorine- and silicon-containing monomers into the polymer chain through complex copolymerization reactions. These methods generally suffer from problems such as lengthy synthetic routes and cumbersome steps, resulting in high process costs and low efficiency. Furthermore, catalyst residues or unclear structures may affect the uniformity and reliability of the final product's performance.

[0005] Therefore, there is an urgent need in this field to develop a new method with a simple synthesis route, mild conditions, and atom economy to achieve efficient and green modification of PCL by PFCB structural units, thereby expanding its application in the advanced electronics industry.
