with the aims at providing the most state of the art information for directing further
scientific research, possible commercialization and design of cellulosic rubber composites. It has been
found that 1) the surface properties of natural cellulose, hence the compatibility and interface of the
natural cellulose and matrix rubber/plastics, are crucial for the successful development of the composites,
such, physical and chemical modification and additives have been widely attempted to improve the
incompatibility and poor interfacial adhesion between the filler and matrix; 2) the curing characteristics,
mechanical properties, thermal stability and morphologies of the composites are complex but closely
related to not only the interfacial properties, but also the compositions (e.g. the concentration of
cellulosic materials) and other processing parameters; 3) the nature of hydrophilic cellulosic and
hydrophobic matrix rubber and/or plastics requires an accurate introduction of coupling agent, one end
of its structure shall be compatible to hydrophilic and the other to hydrophobic. The reviews on the main
paths and results of study on the advanced nanocellulose reinforced rubber nanocomposites and
sandwiches indicate much potentials and needs for further in-depth studies
