Contents:
Most of the contents in this book represent the fresh achievements of the authors' group on smart hydrogel functional materials. While all chapters can be read as stand-alone papers, together they clearly describe the design concepts, fabrication strategies and methods, microstructures and performances of smart hydrogel functional materials.
Vivid schematics and illustrations throughout the book enhance the accessibility of the theory and technologies involved. This is an ideal reference book for a broad general readership including chemists, materials researchers, chemical engineers, pharmaceutical scientists and biomedical researchers, who are interested in designing and fabricating smart hydrogel functional materials for various application purposes.

Inclusion of metal nanoparticles i. Nanoparticles can also function as cross-linking physical and chemical agents. An applied electric field causes electro-osmotic flow of silica particles, and viscous drag within the fluid results in the mass transport of neutral solutes drugs, proteins, etc. The DMTA test was performed in the compression mode, using disc-shaped samples with a diameter of 11 mm and a thickness of 5 mm.
The storage modulus of PVA hydrogel increases by increasing the kaolinite content. The storage modulus of nanocomposite hydrogel containing 15 wt. The results also showed that the hardness is directly depended to the quantity of kaolinite added to the nanocomposite hydrogel.
In an interesting study carried out by Gaharwar et al. This study demonstrated the potential of silicate —PEG nanocomposite hydrogels in orthopaedic, craniofacial sand dental applications. The results showed the potential of the synthesized nanocomposite to retain the shape of the mold containing them Fig. Moreover, the amount of silicate nanoparticles affected the swelling characteristics of the nanocomposites.
Several other aspects of polymer nanocomposites are currently being intensively investigated, such as the effects of nanofiller on chain dynamics, and the dependence of the final properties on the degree and mode of dispersion Novel hydrogels have been prepared using direct dissolution of chitin at low temperature. The dissolution problem is common for chitin in various solvents. Thus resulted chitin hydrogels showed more stable structure and better biocompatibility. The chitin hydrogels may find wide use in bio-applications, as a result of the more stable structure and better compatibility of chitin than that of its derivatives, such as chitosan.
Smart Hydrogel Functional Materials comprehensively and systematically describes our current understanding of smart or intelligent hydrogel functional. Smart Hydrogel Functional Materials" comprehensively and systematically describes our current understanding of smart or intelligent hydrogel functional.
The effects of monodisperse polystyrene nanoparticle fillers on the network formation, rheological properties and adhesion performance of hydrogel nanocomposites based on polyacrylamide and poly acrylamide-hydroxyethyl methacrylate is investigated. The incorporation of these organo-clays in Polydimethyl siloxane PDMS results in formation of pressure sensitive adhesives.
It was shown that by varying the concentration of the organoisilicate additive to the polymer matrix, a major control over the drug release kinetics and the adhesive properties of the matrix can be enhanced.
Now days the emphasis is to develop transdermal formulations, which are based on natural polymer matrix and for better release technologies in, which the dispersion of the drug is uniform within the transdermal layer. The key to improve the hydrogel technology is to direct the research on the design of efficient drug delievery systems with minimal limitations and easy route of administrations.
