摘要

Abstract

By introducing piezoelectric materials into hydrogel oral dressings

a microelectric field could be generated under stress stimulation

thus facilitating oral wound healing. However

to adapt to the moist and dynamic environment of the oral cavity

traditional "step-by-step" synthesis often requires the combination of materials with different functionalities. Given the property differences between these materials

this strategy typically involves complex experimental procedures and unnecessary energy consumption. In this study

with the concept of "integrated construction"

we innovatively proposed a dual-step photo-induced method and successfully fabricated composite hydrogels with excellent performance. We introduced abundant oxygen vacancies into ZnO

leveraging the enhanced interface dynamics to achieve sustained photo-induced effect. With a double-network polymer framework as a template

this method could achieve the photo-induced spontaneous in-situ synthesis of polydopamine (PDA) within hydrogel without any extra special experimental conditions and complex operation procedures. We conducted a thorough analysis of the mechanism underlying this photo-induced method and applied the as-prepared hydrogel for the treatment of oral wounds

which significantly accelerated the healing process due to the outstanding comprehensive performance of hydrogel. These results suggest novel ideas and theoretical support for the facile construction of high-performance hydrogels based on photodynamic principles

demonstrating immense potential for future applications in wound dressings.
