Abstract:The increasing demand for greener and biodegradable materials leading to the satisfaction of society requires a compelling towards the advancement of nano-materials science. The polymeric matrix materials with suitable and proper filler, better filler/matrix interaction together with advanced and new methods or approaches are able to develop polymeric composites which shows great prospective applications in constructions and buildings, automotive, aerospace and packaging industries. The biodegradability of the natural fibers is considered as the most important and interesting aspects of their utilization in polymeric materials. Nanocomposite shows considerable applications in different fields because of larger surface area, and greater aspect ratio, with fascinating properties. Being environmentally friendly, applications of nanocomposites offer new technology and business opportunities for several sectors, such as aerospace, automotive, electronics, and biotechnology industries. Hybrid bio-based composites that exploit the synergy between natural fibers in a nano-reinforced bio-based polymer can lead to improved properties along with maintaining environmental appeal. This review article intended to present information about diverse classes of natural fibers, nanofiller, cellulosic fiber based composite, nanocomposite, and natural fiber/nanofiller-based hybrid composite with specific concern to their applications. It will also provide summary of the emerging new OPEN ACCESSPolymers 2014, 6 2248 aspects of nanotechnology for development of hybrid composites for the sustainable and greener environment.

“…It is shown that Al2O3 deposited films improved the oxygen and water vapor barrier performance 18,21,22 . Accordingly, the lowest water vapor transmission rate (WVTR) for paperboards and paper samples are reported for polylactide-coated boards with 25 nm Al2O3 deposition with value of 1±0.2 g·m -2 ·day -1 (at 23°C and 75% relative humidity (RH)) and for polyethylene (LDPF) coated papers with 50 nm Al2O3 deposition with value of 3.1 g·m -2 ·day -1 (at 23°C and 75% RH) respectively 18,21 . It is also reported that 25 nm coatings of Al2O3 on nano-fibrillated cellulose films decreased the WVTR from ~615 g·m -2 ·day -1 to ~400 g·m -2 ·day -1 18 .…”

“…Studies have shown that ALD coatings are perfectly suited to produce high performance permeation barriers on polymeric and porous materials, such as poly (2, 6-ethylenenaphthalate), polylactide (PLA), polyimide, polyethylene films, coated boards, and etc. 14,[17][18][19][20][21] . In this regard Al2O3 is one of the widely studied materials grown by ALD to improve oxygen and moisture barrier properties of synthetic and bio-based plastics, biopolymers, and fiber-based materials 18,21,22 .…”

 ABSTRACTSurface modification of cellulosic paper is demonstrated by employing plasma assisted atomic layer deposition. Al2O3 thin films are deposited on paper substrates, prepared with different fiber sizes, to improve their barrier properties. Thus, a hydrophobic paper is created with low gas permeability by combining the control of fiber size (and structure) with atomic layer deposition of Al2O3 films. Papers are prepared using Kraft softwood pulp and thermomechanical pulp. The cellulosic wood fibers are refined to obtain fibers with smaller length and diameter. Films of Al2O3, 10, 25, and 45 nm in thickness, are deposited on the paper surface. The work demonstrates that coating of papers prepared with long fibers efficiently reduces wettability with slight enhancement in gas permeability, while on shorter fibers, it results in significantly lower gas permeability. Wettability studies on Al2O3 deposited paper substrates, have shown water wicking and absorption over time only in papers prepared with highly refined fibers. It is also shown that there is a certain fiber size at which the gas permeability assumes its minimum value, and further decrease in fiber size will reverse the effect on gas permeability.
