Modification of bacterial cellulose with starch gel cross-linked with borax

In recent decades, with the growing importance of green chemistry, the use of green absorbers suchas cellulose and starch hydrogels in scientific research has significantly expanded. In this study, modification ofbacterial cellulose was conducted to investigate alterations in its mechanical properties and water absorption .therefore, Starch and borax were employed to prepare a starch-borax cross-linked hydrogel and modify thesurface of bacterial cellulose pellicle with starch gel. Analysis of FTIR, tensile strength test, and investigation ofwater absorption indicate that the swelling rate of the pure layer was ۱۴۳۳%, which increased to ۲۰۵۰% for themodified layer, accompanied by a decrease in tensile strength for the modified layer as well.
