| چکیده مقاله |
| In this study, UV-curable hydrogels based on acrylic acid and acrylamide were synthesized and reinforced with vinyltriethoxysilane-modified carbon quantum dots (VTES-CQDs) as multifunctional nanofillers. Incorporation of 0.5 wt% VTES-CQDs imparted strong emission at 460 nm under 375 nm excitation and introduced broad absorption bands in the 300-400 nm range. Rheological analysis revealed a significant enhancement in viscoelastic behavior, while dynamic hydrogen bonds and reversible siloxane linkages enabled rapid and efficient self-healing. The combination of high water absorption, stable fluorescence, and robust self-healing capability transformed the resulting hydrogels into promising smart materials for advanced applications such as biosensing, controlled drug delivery, and intelligent tissue-engineering scaffolds [1-5]. |
