Three types of nanocomposites, depending on how many dimensions of the dispersed particles are in the nanometer range can be distinguished [1]. Particles with three dimensions in the order of nanometers are typically isodimensional, such as spherical silica nanoparticles obtained by in situ sol-gel methods [2,3] or by polymerization promoted directly from their surface [3,4]. They also include semiconductor nanoclusters [5] and others [3]. Nanotubes or whiskers (with dimensions in the nanometer scale and the third forming a larger elongated structure), for example, carbon nanotubes [6] or cellulose whiskers [7,8], are extensively studied as reinforcing phases yielding materials with exceptional properties. The third type of nanocomposites is characterized by only one dimension in the nanometer range. In this case the material is present in the form of sheets of one to a few nanometers thick and hundreds to thousands nanometers long. This family of composites is referred to as polymer-layered crystal nanocomposites.Depending on the nature of the components used (layered structure, organic ions/polymer matrix) and the method of preparation, three main types of composites may be obtained when a layered structure is associated with a polymer [1].If the polymer is unable to intercalate between the layered sheets, a phase-separated composite is obtained, whose properties stay in the same range as traditional microcomposites. Beyond this classical family of composites, two types of nanocomposites can be dis...

“…Relatively low levels of nanocellulose addition tended to create defects in the structure, thus decreasing the elastic modulus. However, amounts greater than 5% yielded a net increase in strength, suggesting the presence of a contiguous network of cellulosic elements within the matrix (Favier et al 1997;Chakroborty et al 2006a,b;Hubbe et al 2008).…”

Cellulose and some cellulose derivatives can play vital roles in the enhancement of the performance of absorbent products. Cellulose itself, in the form of cellulosic fibers or nano-fibers, can provide structure, bulk, water-holding capacity, and channeling of fluids over a wide dimensional range. Likewise, cellulose derivatives such as carboxymethylcellulose (CMC) have been widely studied as components in superabsorbent polymer (SAP) formulations. The present review focuses on strategies and mechanisms in which inclusion of cellulose -in its various formscan enhance either the capacity or the rate of aqueous fluid absorption in various potential applications.
