What is nanocomposites PDF?
A nanocomposite is a composite material, in which one of the components has at least one dimension. that is nanoscopic in size that is around 10 m. Scaling might be helpful: a coin is on order of 1-2 mm. thick, or 10 m; a carbon fibre, commonly used as a reinforcement in sporting goods, is approximately 7.
What are polymer nanocomposites * Your answer?
Polymer nanocomposites (PNCs) may be defined as a mixture of two or more materials, where the matrix is a polymer and the dispersed phase has at least one dimension smaller than 100 nm [1].
What is the current trend in polymer nanocomposites?
Currently, I think functional and high filler content polymer nanocomposites are the current trend.
What is the meaning of nanocomposites?
A nanocomposite is a multiphase material in which, in contrast to microcomposites, one of the phases has one, two, or three dimensions of less than 100nm, or the composite phases have nanoscale distances between them [45].

What is the importance of nanocomposites?
A range of polymeric nanocomposites are used for biomedical applications such as tissue engineering, drug delivery, cellular therapies. Due to unique interactions between polymer and nanoparticles, a range of property combinations can be engineered to mimic native tissue structure and properties.
What are the properties and characteristics of nanocomposites?
Nanocomposites are materials that incorporate nanosized particles into a matrix of standard material. The result of the addition of nanoparticles is a drastic improvement in properties that can include mechanical strength, toughness and electrical or thermal conductivity.
Why study polymer nanocomposites?
In the last few years, worldwide there has been a lot of interest to tailor the structure and composition of materials on sizes of nanometre scale. Therefore a systematic review on the preparation, properties and applications of polymer nanocomposites is extremely important.
How to obtain nanocomposites from nanoparticles?
In the latter method, the nanocomposite can be easily obtained by dispersing an amount of nanoparticles into a solution of the polymer (Oliveira and Machado, 2013;Krepker and Segal, 2017).
What are the properties of nanocomposites?
The properties of nanocomposites such as mechanical, optical, rheological, flame retardancy and dielectric behaviour have been extensively reviewed. Finally the important applications of nanocomposites and their future scope have also been described.
How do you make a polymer-nanocomposite?
Then, the polymer-nanocomposite was prepared by simple mixing and dispersing the nanoparticles into the tetraethoxysilane polymer solution, with the aid of an ultrasonic dismembrator. The application of the polymer-nanocomposite and other polymeric nanodispersions, on laboratory models, was performed by the brushing technique.
