Hierarchical nanocomposites of chitosan crosslinked with glutaraldehyde for the photodegradation of Rhodamine B and sensor activity against Diclofenac
Nanocomposites of Chitosan/Glutaraldehyde (Chit./Glut.) were fabricated using dissipative convective process followed by freeze drying method adding dextran as structural directing agents and reinforcing agents such as TiO 2 and Si Nanoparticles. The as-synthesized composites were characterized by F...

Summary: | Nanocomposites of Chitosan/Glutaraldehyde (Chit./Glut.) were fabricated using dissipative convective process followed by freeze drying method adding dextran as structural directing agents and reinforcing agents such as TiO

and Si Nanoparticles. The as-synthesized composites were characterized by Fourier transform infrared (FT-IR) spectroscopy, Powder X-ray diffraction (PXRD), Scanning electron microscopy (SEM), Transmission electron microscopy (TEM), and Mechanical strength. Composites bear significant load with the increase of stress except in the case of Chit./TiO
