Abstract

Nanocellulose materials are expected to partly replace petroleum-derived carbon black in rubber composites for the short-term improvement of their properties. In this study, phosphorylated cellulose nanofibers (P-CNFs) and hydrogenated nitrile-butadiene rubber (HNBR) were oven-dried with or without metal (meth)acrylates, and the once-dried mixtures were kneaded and pressed to prepare cross-linked HNBR/P-CNF/metal (meth)acrylate composite sheets. Neat HNBR and carbon-black-containing HNBR composite sheets were prepared as references. In addition to the tensile and dynamic thermomechanical properties, the, hardness, abrasion resistance, degree of hysteresis loss, and hot water/organic solvent resistance of the composite sheets were evaluated. The properties of the P-CNF containing composite sheets were better than those of the neat HNBR sheet and carbon-black-containing composite sheets at the same P-CNF or carbon black content. The HNBR/P-CNF/zinc methacrylate composite sheets showed the best performance in terms of not only the above properties, but also the hot water resistance, tensile properties, and abrasion resistance.

期刊介绍： Polymer Degradation and Stability deals with the degradation reactions and their control which are a major preoccupation of practitioners of the many and diverse aspects of modern polymer technology. Deteriorative reactions occur during processing, when polymers are subjected to heat, oxygen and mechanical stress, and during the useful life of the materials when oxygen and sunlight are the most important degradative agencies. In more specialised applications, degradation may be induced by high energy radiation, ozone, atmospheric pollutants, mechanical stress, biological action, hydrolysis and many other influences. The mechanisms of these reactions and stabilisation processes must be understood if the technology and application of polymers are to continue to advance. The reporting of investigations of this kind is therefore a major function of this journal. However there are also new developments in polymer technology in which degradation processes find positive applications. For example, photodegradable plastics are now available, the recycling of polymeric products will become increasingly important, degradation and combustion studies are involved in the definition of the fire hazards which are associated with polymeric materials and the microelectronics industry is vitally dependent upon polymer degradation in the manufacture of its circuitry. Polymer properties may also be improved by processes like curing and grafting, the chemistry of which can be closely related to that which causes physical deterioration in other circumstances.
