About the Lecture

Currently, the problem of “white pollution” caused by the degradation-resistant character of synthetic plastic membranes has received a great deal of attention in the research on membrane materials derived from biomass. Tara gum is procured from the endosperms of caesalpinia spinosa seeds, a polysaccharide of high molecular weight mainly composed of galactomannan, with excellent membrane-forming properties. However, there are still some drawbacks in terms of strength and moisture-resistance. This lecture will elaborate on the synthesis, features and properties of nanocellulose-reinforced tara gum composite membranes. On this basis, the natural and non-toxic ingredients extracted from plants act as pH response factor to synthesize visible color-changing membranes and research on the sensitivity of response membranes and their rudimentary applicable properties.
