Abstract:
... A novel rosin-based ester tertiary amine (RETA) with three hydrophilic groups and a rigid hydrophobic group was synthesized from rosin by Diels-Alder addition, acylation and esterification reactions. RETA was characterized by infrared spectroscopy (FT-IR) and proton nuclear magnetic resonance spectroscopy (13C NMR). Results from testing surface tension, zeta potential, and transmission electron sp ...

Subject:
Gleditsia sinensis; ambient temperature; functional properties; galactomannans; light scattering; molecular weight; nitrogen; rheometers; scanning electron microscopy; viscosity
Abstract:
... The apparent viscosity, molecular weight, and molecular weight distribution are important physical properties that determine the functional properties of galactomannan gum. Gleditsia sinensis gum (GSG) in semi-solid state was pressure cell treated over a range of temperature (30–110°C) under nitrogen maintained at a pressure of 1.0–4.0MPa. Physicochemical properties of GSG samples both before and ...

Abstract:
... Cellulose-derived materials are usually characterized by sophisticated structures, leading to unique and multiple functions, which have been a source of inspiration for the fabrication of a wide variety of nanocomposites. Cellulose nanocrystals/poly(acrylamide) (CNCs/PAM) nanocomposite hydrogels were synthesized via in situ polymerization in the CNC suspension. The cellulose from pulp fiber under ...

Abstract:
... The unique combinations of hard and soft components with core/shell structures were proposed to synthesize high strength nanocomposite hydrogels. The elastomeric hydrogels containing rod-like cellulose nanocrystals (CNCs) core and polyacrylamide shell were made from aqueous solutions via free radical polymerization in the absence of chemical cross-links. The obtained hydrogels possessed greater te ...
