other polymer systems, like starch, are very inexpensive, but have fairly poor mechanical properties. one way to provide a successful polymeric material at a reasonable cost is by creating blends or nanocomposites. for this work, solid state shear pulverization (sssp) was used to process the polymeric materials.
a new approach to reducing the flammability of layered double hydroxide (ldh) based polymer composites: preparation and characterization of dye structure intercalated ldh and its effect on the flammability of polypropylene grafted maleic anhydride/d ldh composites (wpcs) as potential fire safe bio based materials for building products
the authors have succeeded in developing new green nanocomposites with improved properties. graphene oxide reinforced thermoplastic starch based (tps/go), green nanocomposites were successfully prepared with different loadings of graphene oxide (0.1, 0.2, 0.5 and 1%) by melt extrusion followed by injection molding technique.

his research interests include the synthesis and processing of biobased polymers, nanomaterials, polymer micro/nanocomposites, nanoelectronic materials, novel high dielectric constant materials, electrochromic materials for energy storage, green synthesis of nanomaterials, and surface functionalization of polymers/nanomaterials.
nevertheless, the worldwide abundance of starch, the simplicity of the hydrolysis process, and the absence of a direct influence of nanocomposites fabrication on final macroscopic properties, (this latter point is to be further investigated) provide ample reason to expect the development of a vast array of applications based on these materials.
a series of superabsorbent polymer composites (sapcs) were synthesized via emulsion polymerization of partially neutralized acrylic acid onto polystyrene in the presence of hectorite (ht) clay powder and mung bean starch (mbst) using ammonium persulphate and n'n, methylenebisacrylamide as initiator and crosslinker, respectively. the aim of this study is to prepare a hydrogel composite using
volume b forms one volume of a handbook about polymer nanocomposites. volume b deals with carbon nanotube based polymer composites. the preparation, architecture, characterisation, properties and application of polymer nanocomposites are discussed within some 25 chapters. each chapter has been authored by experts in the respective field.
however, this material displays some drawbacks compared to conventional polymers, such as limited processability and high stiffness and brittleness. blending of starch with other synthetic, biodegradable, thermoplastic polymers could lead to the development of a new range of environmentally friendly polymeric materials with improved properties.

· a polymer fractal. go green, go natural! when it comes to polymers, green and natural are not the same.as their name implies, natural polymers (or biopolymers) are polymers that occur naturally or are produced by living organisms (such as cellulose, silk, chitin, protein, dna).by a wider definition, natural polymers can be man made out of raw materials that are found in nature.
