**4. Conclusion**

This work used a facile approach to prepare PVA/AE/QCS composites used as a multifunc‐ tional wound‐dressing materials exhibiting strong antibacterial property, good moisture maintenance, and excellent biocompatibility for wound healing. The mass ratio of PAQ composites was controlled at three different levels of 6:3:1, 7:2:1, and 8:1:1 (PVA/AE/QCS). Material characterization of PAQ composites shows that PAQ composites possess a porous profile on both surface and cross‐section areas with 3–60‐μm pore size and a 3D porous network inside, in which PAQ composite with a mass ratio of 7:2:1 exhibits more homogeneous porous structure. Such a homogeneous porous structure could effectively prevent the invasion of microorganism, as well as readily absorb extrudes from wound. FTIR and TGA results indicate that AE and QCS have been successfully bound to PVA matrix, and the addition of AE and QCS to PVA is conducive to the enhancement of thermal stability of composites. All the PAQ composites exhibit excellent water absorbability over 10 times higher than their dry weight in both PBS (pH 7.4) and HAc‐NaAc buffer (pH 5.0). The PAQ composites exhibited an excellent antibacterial characteristic and a good biocompatibility of fibroblasts. In consid‐ eration of cost and results from material characterization plus antibacterial property and biocompatibility, the PAQ2 composite with a mass ratio of 7:2:1 exhibits relatively satisfactory thermal stability and antibacterial property plus fewer amounts of AE and QCS, and thereby it would become a competitive multifunctional wound dressing.
