Abstract Thermochromic smart windows offer energy‐saving potential through temperature‐responsive optical transmittance adjustments, yet face challenges in achieving anti‐UV radiation, fast response, and high‐temperature stability characteristics for long‐term use. Herein, the rational design of Hofmeister effect‐enhanced, nanoparticle‐shielded composite hydrogels, composed hydroxypropylmethylcellulose (HPMC), poly( N,N ‐dimethylacrylamide) (PDMAA), sodium sulfate, polydopamine nanoparticles, anti‐UV, fast‐response, all‐day‐modulated is reported. Specifically, a three‐dimensional network PDMAA created as supporting skeleton, markedly enhancing thermal pristine HPMC hydrogels. Sodium sulfate induces effect, lowering lower critical solution temperature to 32 °C while accelerating phase transition rates fivefold (30 s vs. 150 s). Intriguingly, small‐sized nanoparticles simultaneously enable high luminous 66.9% outstanding capability. Additionally, window showcases solar modulation (51.2%) maintains 10.2 reduction versus glass during all‐day applications. The strategy effective, opening up new avenues manufacturing fast‐response durable thermochromic energy savings emission reduction.
