Hydrogel, as a three-dimensional material with high water content, has unique physicochemical and variable mechanical properties. Natural polysaccharide-based composite hydrogels are very popular within medical industry as these viscoelastic materials are non-toxic, biodegradable, bioabsorbable, and biocompatible. This research investigates the engineering of novel composite hydrogels from natural polysaccharides salecan and curdlan without any structural modification and chemical crosslinking. The scanning electron microscopy, Fourier transform infrared spectroscopy and various rheological methods were employed to investigate the morphology, molecular interaction, and flow behavior of the samples respectively. The key rheological parameters were compared using the Power Law, Herschel-Bulkley and Arrhenius models. This is the first study reporting a novel composite hydrogel made from Salecan and Curdlan with ideal elasticity, enhanced thermostability, good injectability, self-recovery and other rheological properties that will pave the way for application in different fields.

UI MeSH Term Description Entries
D008855 Microscopy, Electron, Scanning Microscopy in which the object is examined directly by an electron beam scanning the specimen point-by-point. The image is constructed by detecting the products of specimen interactions that are projected above the plane of the sample, such as backscattered electrons. Although SCANNING TRANSMISSION ELECTRON MICROSCOPY also scans the specimen point by point with the electron beam, the image is constructed by detecting the electrons, or their interaction products that are transmitted through the sample plane, so that is a form of TRANSMISSION ELECTRON MICROSCOPY.
