Nanocellulose has prompted extensive exploration of its applications in advanced functional materials, especially humidity-responsive materials. However, the sunflower pith (SP), a unique agricultural by-product with high cellulose and pectin content, is always ignored wasted.

Abstract If optical probes with different sensitivity could be performed simultaneously in their hard states (e.g., film), soft gel), and solution states, sensing accuracy enhanced due to the highly mutual calibration. The biomass of cellulose nanocrystals is less compatible commonly used organo‐fluorescent dyes require chemical modification improve application performance, but this leads less‐effective material cost. In work, depending on electrostatic attractions between negatively charged polymer matrix cationic dyes, (CNCs)‐based emissive membranes were prepared by vacuum filtration method. Then, resulting materials transformed into hydrogels, or dispersed water solutions, further absorbed commercially available spheres filter papers, devices states. It worth mentioning that preparation process does not addition organic dispersants, thus greatly reducing Finally, behaviors toward several important stimuli, such as temperature, pollutants like Cr (VI) pH changes, successfully carried out. Overall, our research works highlighted a processable way fabricate fluorescent, water‐dispersible, portable, long‐time‐storable, cost‐effective sensors meet versatile requirements.
