Nanotechnology has facilitated unique ways of developing novel nano-composites. In that sense, polymer-based nano-composites are being extensively researched for their outstanding properties as a result of incorporating nano-fillers in the polymer matrix. They have activated enormous research interests owing to their potential in addressing environmental issues, packaging, optics, electronics, battery electrolytes, pneumatic actuation, molecular separations, sensors, biomedical applications, etc. Hence, the authors intend to consolidate reported information about these polymer matrices, diverse inorganic nanofillers, and nano-filled polymer composites for improvement in properties and future advanced applications. The review exhaustively covers 15 years of literature on theoretical, experimental, and application aspects of PVA & PMMA-based nano-composites. It also summarizes the structure-property correlations that govern their performance. Hence this review is hoped to provide the readers with stimulating insights on strategies, noteworthy challenges, and future opportunities/prospects in developing polymer nano-composites that may cater to the need of our society and scientific industries as well.

This study was an attempt to combine fused deposition modelling and hot press moulding technique to fabricate hybrid polymer composites using acrylonitrile butadiene styrene (ABS) polymer, woven glass fibre (GF) and woven carbon fibre (CF). The composite specimens were subjected towere subjected to mechanical and thermal characterization.Tensile strength of GF/ABS and GF/CF/ABS composite were far higher than the virgin ABS. GF/ABS composites displayedimproved thermal resistance by giving a final residue of 42.36%, followed by GF/CF/ABS hybrid composites as per the thermogravimetric analysis. Thermomechanical analysis revealed the coefficient of thermal expansion in the order: ABS > GF/ABS > GF/CF/ABS. The entropy obtained from the DSC curve was of higher value for composites than the ABS. The ABS based composites fabricated from this technique can be applicable to structural parts in the automobiles, aircrafts, shipping vessels, etc.
