外文摘要：A kind of smart calcium alginate fiber having pH indicating properties was proposed to monitor wound healing. The smart calcium alginate fiber was prepared by dyeing the hydroxypropyl trimethyl ammonium chloride chitosan (HACC) modified calcium alginate fiber with alizarin dye and anthocyanin dye, respectively. It was worth noting that modification of calcium alginate fibers with HACC enhanced the dyeing and antibacterial properties, simultaneously. When the concentration of HACC was 10 g/L, the modified calcium alginate fiber had the best dyeing performance. At the same time, the dyeing process had no significant influence on the mechanical properties of the fibers with the strength loss only around 0.2 cN/dtex. The smart calcium alginate fibers exhibited a rapid and significant color change and reversible color response at pH 2-11. Moreover, the color change could be easily observed by naked eye. Therefore, the prepared calcium alginate fibers could be a good candidate for intelligent wound dressings for visual monitoring of wound healing. [GRAPHICS] .
