In this study, naturally derived coated urea with temperature‐responsive behavior (SNCU) was fabricated using castor oil/polycaprolactone (PCL2000) blends and isocyanate, nano‐SiO2 and siloxane were employed to enhance its hydrophobicity. Nutrient (N)‐release experiments were conducted at various temperatures to explore the temperature‐responsive behavior of the coated urea. The temperature‐response mechanism and composition of the coated urea were investigated using x‐ray diffraction (XRD), x‐ray photoelectron spectroscopy (XPS), simultaneous thermal analysis (DSC), and Fourier‐transform infrared (FT‐IR) spectroscopy. Results indicated that PCL2000 incorporation could produce a block polymer with a two‐phase structure consisting of a crystalline and an amorphous phase, and the SNCU exhibited a significant temperature switch at 32.5°C. Moreover, the N‐release SNCU longevity increased to 70 days. Therefore, the findings from this work highlight that temperature‐responsive SNCU, with its higher N availability, could be suitable for agricultural applications in sustainable, green agricultural development. 10.1002/app.56721 http://onlinelibrary.wiley.com/termsAndConditions#vor |
