Herein, a chemical-physical dual strategy is proposed by introducing fluorine and silica nanoparticles into a traditional polyimide aerogel to reshape both the chemical and microstructure and give birth to fluorine and silica functionalized polyimide composite aerogels (FSPI), showing PDRC with inherent flammability and ultraviolet radiation resistance. Owing to the presence of fluorine and silica, the FSPI aerogels show high solar reflectance (∼92.8 %) in the wavelength of 0.78–1.1 μm and high IR emissivity (∼93.0 %) among 8–13 μm, thus fulfilling a passive sub-ambient cooling of ∼9.4 °C at daytime. Meanwhile, the fluorine and silica also endow the FSPI with outstanding thermal stability (T<sub>-5 %</sub>, ∼524 °C), hydrophobicity (water contact angle ∼120.4°), anti-aging, and flame-retardant (PHRR, 13.1 W g<sup>−1</sup>) performances, making them ideal candidates for sustainable cooler in building energy saving.

However, the high cost of fibers used to enhance the ductility of EGC hinders its engineering applications. In this study, economical EGCs with hybrid PE fibers were developed to meet this challenge by utilizing low-cost, low-modulus PE fibers (PE40) to partially or fully substitute for the conventional high-cost, high-modulus PE fibers (PE110). Compressive, uniaxial tensile and single fiber pull-out tests were performed on EGCs with different PE40 fiber replacement ratios (0 %, 30 %, 50 %, 70 % and 100 %) to investigate the mechanical properties. Scanning electron microscopy (SEM) was further employed to examine the bridging effect between the fiber and matrix. Additionally, the sustainability and economic potential of EGCs at various PE40 fiber replacement ratios were also evaluated. The results indicate that replacing PE110 fibers with PE40 fibers can enhance the compressive strength of EGCs. Notably, EGCs with PE40 replacement ratios ranging from 30 % to 100 % demonstrated typical strain-hardening behavior. It is noteworthy that the EGC with 100 % replacement ratio of PE40 fibers still retains a high tensile strain capacity of 5.81 %, exhibiting 43 cracks with a well-controlled crack width of approximately 108 μm. The environmental impact of EGC with hybrid fibers is extremely low, and the cost is significantly lower compared to EGCs/ECCs with the same fiber volume fraction.
