Effect of Moisture on Cohesion Strength of Carboxymethyl Cellulose Powder
The impact of moisture content on cohesion strength is measured using the TA Instruments Powder Rheology Accessory. It was found that as moisture content increases, cohesion strength also increases, demonstrating the importance of controlling humidity during processing.
Using an ARES Rheometer to investigate the β-relaxation change of graphene poly(ethyl methacrylate) nanocomposite
Here we describe the application of an ARES Rheometer (TA Instruments) with a rectangular torsion fixture, to investigate the β-relaxation change of poly (ethyl methacrylate)/ graphene oxide. It is observed that graphene increases both the glass transition and the β-relaxation temperature, but the β-relaxation to a lesser extent.
