The attachment and morphology observation in the 3‐day cultivation of HFCs on pure PVA and PAQ composites were analyzed as shown in **Figure 8**. All the samples show good attachment of HFCs on their substrates. A slightly preferable viability of HFCs is found in PAQ composites as compared to pure PVA, although no significant viability is present, suggesting that the impact of QCS against cell growth has been offset by AE which shows a potential of facilitating the growth of fibroblasts. L929 fibroblasts show a good morphology of extended shape on all the substrates, which suggests that either pure PVA or PAQ composites are satisfied substrates for the attachment and growth of L929 fibroblasts. In the light of the results from antibacterial assays and biocompatibility plus the analyses from SEM, FTIR, TGA, and water absorbability, considering the cost, the PAQ2 with a mass ratio of PVA:AE:QCS (7:2:1) exhibits relatively satisfactory properties and thereby it should become the optimal material

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

composition.
