摘要： The research and development of a pesticide intelligent controlled release system not only represents one of the key technologies for promoting the advancement of green agriculture but also serves as an essential driving force in advancing agricultural science and technology. In this study, we successfully developed a temperature-responsive intelligent controlled release system based on the working principle of the CorA transporter found in living organisms. Using host-guest interaction, we packed temperature-responsive pillar[n]arenes-polymer into nanopores to construct an efficient temperature-responsive controlled release membrane. The channel can be activated or deactivated by adjusting the size of the pillar[n]arenes-polymer. This membrane has good cycling stability and can control the release of three different pesticides. Moreover, the controlled release system can regulate the release of pesticides at varying rates to satisfy the requirements for different pesticide concentrations, and the release rate of tebuconazole reaches 4.97 μM·h−1·cm−2 at 55 °C and 6.48 μM·h−1·cm−2 at 75 °C. Furthermore, by addressing issues related to poor stability and high costs associated with biological channels through developing this biomimetic channel membrane, we have provided robust support for both effective pesticide utilization and sustainable advancements in green agriculture.
