“…-Moisture resistance: the homogeneous dispersion of high-aspect-ratio silicate layers (a) introduces tortuous and thus longer pathways through the starch polymer matrix for the diffusion of water molecules (Cyras et al 2008;Dai et al 2009a;Ibrahim 2011;Lilichenko et al 2008;Maksimov et al 2009;Mondragón et al 2008;Park et al 2003;Tang et al 2008c;Wang et al 2009bWang et al , 2010b and also (b) causes the shielding of the exposed water-sensitive hydroxyl groups of the starch (M€ uller et al 2011;Wang et al 2009bWang et al , 2010b, both of which contribute to a reduction in the moisture sensitivity. -Oxygen barrier property: a higher oxygen barrier can be ascribed to the silicate layers inducing a higher tortuosity and longer diffusion pathways for oxygen molecules (Lilichenko et al 2008;Maksimov et al 2009;Zeppa et al 2009).…”

“…-Oxygen barrier property: a higher oxygen barrier can be ascribed to the silicate layers inducing a higher tortuosity and longer diffusion pathways for oxygen molecules (Lilichenko et al 2008;Maksimov et al 2009;Zeppa et al 2009). -Thermal stability: improvement in the thermal stability can be due to several concomitant phenomena such as (a) the higher thermal stability of the inorganic phase (phyllosilicate) compared to the organic one (starch), (b) the phyllosilicate acting as a heat barrier which enhances the overall stability (Cyras et al 2008;Ibrahim 2011), (c) the increase in the tortuosity of the diffusion pathways for oxygen and the combustion (pyrolysis) gas (Alexandre and Dubois 2000;Chiou et al 2007;Chivrac et al 2010d;Cyras et al 2008;Namazi et al 2009;Xu et al 2005), and (d) the reorganization of the starch structure with less exposed hydroxyl groups and thus less susceptibility to degradation (Pandey and Singh 2005;Wang et al 2010b;Wilhelm et al 2003b).…”

“…Glycerol has been a widely used plasticizer in the preparation of starch-phyllosilicate nanobiocomposites (Bagdi et al 2006;Chiou et al 2007;Chivrac et al 2008aChivrac et al , b, 2009bChivrac et al , 2010aCyras et al 2008;de Carvalho et al 2001;Huang et al 2004;Ibrahim 2011;Kampeerapappun et al 2007;Lilichenko et al 2008;Liu et al 2011c;Andrade 2009, 2010;Maksimov et al 2009;Mondragón et al 2008;M€ uller et al 2011;Pandey and Singh 2005;Park et al 2002Park et al , 2003Tang et al 2008b, c;Wang et al 2009b, d;Wilhelm et al 2003b;Zeppa et al 2009;Zhang et al 2007). It has been demonstrated in the previous studies (Cyras et al 2008;Park et al 2002) that, because of the strong polar interactions between the hydroxyl groups from the starch polymer chains, from the glycerol, and from the silicate layers, glycerol and/or starch chains can enter into silicate interlayers to form intercalated starch-MMT nano-biocomposites.…”

Starch as a biopolymer directly extracted from nature has received much attention in recent years due to its strong advantages such as low cost, wide availability, renewability, and total compostability without toxic residues. Starch-based materials always display properties that are less satisfactory than those of traditional polymer materials, which can be ascribed to the inherent characteristics of starch. To make such materials to be truly competitive and to widen its applications, the development of starch-based nano-biocomposites could be a promising solution. This chapter provides the fundamental knowledge related to starch-based nano-biocomposites as well as the most recent developments in this area. Various types of nanofillers that have been used with plasticized starch are discussed such as montmorillonite, cellulose nanowhiskers, and starch nanoparticles. The preparation strategies for starch-based nano-biocomposites with these types of nanofillers and the corresponding dispersion state and related properties are also largely discussed.

Morphologies and properties of nanocomposite films based on a biodegradable poly(ester)urethane elastomer

Biodegradable poly(ester)urethane (PU) elastomer-based nanocomposite films incorporated with organically modified nanoclay were prepared with melt-extrusion compounding followed by a casting film process. These films were intended for application as biodegradable food packaging films, with their enhanced gas barrier, mechanical, and thermal properties and good flexibility. From both X-ray diffraction measurements and transmission electron microscopy observations, the coexistence of intercalated tactoids and exfoliated silicate layers in the compounded PU/clay nanocomposite films was confirmed. In addition, the morphology exhibited a clay dispersion state in the matrix and was influenced by the incorporated nanoclay content. The effects of the nanoclay loading level on the thermal, mechanical, and barrier properties of the compounded nanocomposites were also investigated. As a result, it was revealed that the addition of nanoclay up to a certain level resulted in a remarkable improvement in the thermal properties in terms of thermal stability and the degree of thermal shrinkage; mechanical properties, including dynamic storage modulus and tensile modulus; and oxygen/water-vapor barrier properties of the nanocomposite films.

Investigation of the improvement of the physical and mechanical properties of polymer composite materials with nano‐sized powders

Polymer composites are widely applied in modern aviation. However, their shortcomings force scientists to look for material enhancing methods. Therefore experimental research of the influence of nanoparticles on the polymer strength and the electromagnetic properties was conducted. The polymer modification was realized by two kinds of nano-sized powders: iron and diamond. The addition of 0.67 % nanodiamonds mass content in polymer increases its strength (about 2 times). This can be explained by electrical interaction of nanoparticles with high specific surface energy and monomer molecules having dipole moments. The samples for dielectric permittivity measuring were made from pure resin and from resin reinforced with 0.67 % nanodiamonds and 1 % nanoiron mass content. The results show that the addition of nanodiamonds decreases the resin dielectric permittivity but nano-iron addition increases it. The electrical conductivity r and the magnetic permeability l were measured on samples with 1 %, 3 %, 10 % and 25 % weight content of nanoscale iron. The electrical conductivity did not uniformly increase according to the percolation theory. This percolation transition (by 5 orders of magnitude) corresponds to nano-iron mass content 3 %.
