Ultra-light porous 3D network rectorite (Rec) gels were prepared by crosslinking chitosan with glutaraldehyde in a simple process of aqueous gel precursor freezing, solvent exchange, and ethanol drying instead of expensive supercritical drying technology. The porous structures of Rec gels were composed of randomly oriented Rec layers. Rec gels with densities of 28.8 to 79.6mg/cm3 withheld liquids...
A starch/carboxylated multiwall carbon nanotube (CCNT) composite (CCNT–starch) was prepared by covalently grafting a natural polymer starch onto the surfaces of CCNT. The obtained CCNT–starches were characterized by Fourier transform infrared spectroscopy (FTIR), thermogravimetric analysis (TGA), transmission electron microscopy (TEM), ultraviolet–visible spectroscopy (UV–vis) and electrochemical...
