“…Different nanocomposites based on microfibrillated cellulose or bacterial cellulose have been prepared with petroleum-derived nonbiodegradable polymers such as polyethylene (PE) or polypropylene (PP) and also with biodegradable polymers such as PLA, polyvinyl alcohol (PVOH), starch, polycaprolactone (PCL), and polyhydroxybutyrate (PHB). Thakur et al [46][47][48][49]51] prepared the graft copolymers from cellulose fibers and methylmethacrylate (MMA) [46,51]. Thakur et al [50] also modified the surface properties of natural cellulosic biomass by the graft copolymerization technique [50].…”

Nanocomposites are the most important field of research nowadays. Metal nanoparticles have attracted continuous interest owing to their unusual properties and potential uses in electronics, optics, magnetics, catalysts, and sensors. Green synthesis (for noble metals, such as, gold, silver, platinum, palladium, etc.) and characterization of nanoparticles have emerged as a significant field of nanotechnology. As a well-known noble metal, gold is widely investigated due to its specific impact in the fields of biotechnology and bioscience. Gold nanoparticles (GNP) being the most stable metal nanoparticles have the advantages of (a) easy synthesis, (b) colloidal stability, and (c) ability to be easily conjugated with biological molecules. Gold nanoparticles also present fascinating aspects such as the behavior of the individual particles, size-related electronic, magnetic and optical properties (quantum size effect), and their applications to catalysis and biology. A large number of polymer molecules were selected to decorate the surface of gold nanoparticles in physical or chemical ways for different purposes. Gold nanoparticle-reinforced nanocomposites were prepared using different polymer matrices for different types of applications such as catalytic applications, optoelectronic and magneto-optic applications, biological, medicinal applications, etc.

“…Mixtures with more than 85% starch can be used in injection molding and foam manufacturing. 33 Starch-based composites and starch structure have disadvantageous physical properties, for example, high hydrophilicity, high biodegradability, low thermal strength, and low decomposition temperature. 34 Therefore, in the manufacturing of starch-based composites, modification of the starch structure may sometimes be required.…”

“…In this technique, bio-based additives are introduced into the preformed mold, and matrix resin is applied to the fiber with simple hand tools such as a brush. In the hand lay-up method, the fiber or fiber-structured additive is deposited on a mold and impregnated with liquid resin. − This process is continued until the desired thickness of the material is obtained. In particular, this technique is frequently used in polyester, epoxy resins, vinyl ester, and phenolic resins.…”

Researchers have recently focused on the advancement of new materials from bio-renewable and sustainable sources because of the great concerns about environmental, waste accumulation and destruction, and the inevitable depletion of fossil resources. The bio-renewable-based materials have been extensively used as a matrix or reinforcement in many applications. In the development of innovative methods and materials, composites offer important advantages because of their excellent properties such as ease of fabrication, higher mechanical properties, high thermal stability, and many more. Especially, the nanocomposites (obtained by using biorenewable sources) have significant advantages when compared to conventional composites.The nanocomposites have been utilized in many applications ranging from food, biomedical, electroanalysis, energy storage, wastewater treatment, automotive etc. This comprehensive review provides chemistry, structures, advanced applications and recent developments about nanocomposites obtained from bio-renewable sources.

“…Many types of grafting polymerization techniques have been developed in recent years by gamma ray irradiation, electron beam irradiation, proton beams, ultraviolet light and plasma polymerization [2] . But, radiation grafting is the most important method for modification of the chemical and physical properties of polymeric materials and also for synthesis of hydrophilic membranes by selecting a suitable polymer film as substrate [3] . By selective variation of the reaction conditions, the grafting of acrylic acid (AAc) may be carried out not only on the surface but also within the polymer matrix [4] .…”

Low density polyethylene films were grafted by poly (acrylic acid). The effects of dose, monomer concentration, solvent, inhibitor and thickness of films were investigated. Adsorption capacities of grafted films of Pb 2þ and Cd 2þ reached up to 20 and 13 (mg/g), respectively. The complexed grafted films in protection of workers against technetium-99 m radiation dangers were investigated. The effects of grafting percentage, thickness and adsorption capacity of ions on shielding efficiency were studied. The transmission intensity of complexed grafted films decreased gradually until arrived almost 0%. The protection efficiency of complexed grafted films is higher than grafted and virgin films, respectively.
