Multifunctional sprayable hydrogels are widely developed for daily chemical and biomedical application. However, adding functional components and active ingredients is difficult to achieve uniform distribution and controlled release. Here, a new kind of lignin‐based nanoparticles is prepared, which can give hydrogels more functions (anti‐ultraviolet and antioxidant properties) and promote the response of hydrogels to pH stimulus. The nanocomposite hydrogels are engineered using carboxymethyl chitosan (CS) and trans ‐resveratrol‐loaded lignin‐based nanoparticles (LRNPs). The rheological, anti‐ultraviolet, and antioxidant properties of the sprayable hydrogel can be fine‐tuned by varying the ratio of lignin‐based nanoparticles. More importantly, the release behavior of the active ingredient can be flexibly controlled by adjusting the pH environment. This work provides a facile approach to fabricate a green and intelligent sprayable hydrogel amenable to a great potential in daily chemical and biomedical area.
