Composite nanocomposite

The synthesized nanostructured composites (nanocomposites) (MgH -i- LiAlH ) were subjected to desorption experiments after ball milling for 20 h. Figure 3.34 shows desorption curves obtained under continuous heating up to 300°C (quasi-TPD)...

The estimated values according to Eq. (6.32) are v = 0.462 for the dependence E hJ first part and v = 0.216 for the second one. If for the first part the value v is close to Poisson s ratio magnitude for nonfilled rubber [36], then in the seeond part, the additional estimation is required. As it is known [48], a polymer composites (nanocomposites) Poisson s ratio value can be estimated according to the equation as in what follows ... 

The estimations according to Eq. (1.32) gave for the dependence E h ) for the first part n = 0.462, for the second part n = 0.216. If for the first part the value of n is elose to the value of Poisson s ratio for non-filled rubber, then for the second part, the additional estimation is required. As is known, the Poisson s ratio value (v ) of a polymer composite (nanocomposite) can be estimated according to the following equation ... 

Yang et al used a low viscosity resin solution which was allowed to infiltrate the buckypapers to impregnate the SWNT rope networks. A hot-press moulding process was used for moulding and euring to produce the final composites. Nanocomposites with preformed tube networks and high SWNT...

Along with these, researchers have also focused their work on the processing of nanocomposites (materials with nanosized reinforcement) of biobased materials to improve their physical properties. Analogous to orthodox composites, nanocomposites also use a matrix where the nanosized reinforcement elements are dispersed. The reinforcement is cmrently achieved by a nanoparticle, where at least one of its dimensions is lower than 100 nm. This particular feature provides nanocomposites with unique and outstanding properties never found in conventional composites. Biobased nanocomposites are the next generation of materials. 

Various synthetic materials have been and are still being used as packaging raw material, which may have many disadvantages. However, different polymers obtained from agricultural products are very suitable for the formulation of packaging materials. These polymers such as polysaccharides can be used in different forms like coatings, films, composites, nanocomposites, etc. Cellulose is one of the most abundant polysaccharides on earth, with an attractive combination of different properties. However, the efficient use of cellulose as a raw material for packaging seems rational and is a subject that should be taken into consideration. 

In all materials used in different aspects of cellulose applications in food packaging, the material characteristics including cellulose, plasticizers, etc., and the fabrication procedures like composites, nanocomposites, casting of a film-forming solution, thermoforming, and so on, must be adapted to each specific food product and the conditions in which it will be used such as relative humidity, temperature, etc. Furthermore, edible and biodegradable films must meet a number of specific functional requirements like moisture barrier, gas barrier, water solubility, color and appearance, nontoxicity, etc.
