“…As reported in the literature, uniform dispersion of a nanofiller in a starch matrix and strong interfacial adhesion through hydrogen bonding between the nanoparticles and the matrix could normally be achieved, especially for polysaccharide-encapsulated metal nanoparticles due to the similar chemical structures of the stabilizer and the matrix Liu et al 2011a;Ma et al 2009;Yu et al 2009;Zheng et al 2009a). As a result, improvement in the performance could be normally observed, even though some aspects of property deterioration have also been reported.…”

“…-Mechanical properties: increases in the tensile strength Liu et al 2011a;Ma et al 2009;Wu et al 2009b;Yu et al 2009;Yun et al 2011;Zheng et al 2009a), Young's modulus Yu et al 2009), and the storage modulus (DMA) Yu et al 2009) and a decrease in the elongation at break Liu et al 2011a;Zheng et al 2009a) have been reported. These could be ascribed to the decreased mobility of the polymer chains in the presence of the nanofiller, which has strong interactions with the matrix (ZnO Yu et al 2009), ZrO 2 ·nH 2 O ).…”

“…-Thermal stability: a decrease in the thermal decomposition temperature but an increase in the residual weight at the end of thermal decomposition was observed for nano-biocomposites reinforced by ZrO 2 ·nH 2 O , CdS (Radhakrishnan et al 2007), CdSe (Božanić et al 2009), and Sb 2 O 3 ). While Liu et al (2011a) and Chang et al (2009) ascribed this to the poor thermal stability of the CMC in the nanoparticles, Radhakrishnan et al (2007) and Božanić et al (2009) explained that the increased hydroxyl groups (due to the presence of the nanoparticles which broke the intermolecular interactions of the starch matrix) Polysaccharides DOI 10.1007/978-3-319-03751-6_50-1 # Springer International Publishing Switzerland 2014 could result in thermal condensation between them, which could consequently direct the reaction toward carbonization instead of the formation of volatile components (Zhang et al 2002), -UV-visible light absorbance/transmittance: compared to the pure starch matrix, nanobiocomposites reinforced by ZnO Yu et al 2009) and Sb 2 O 3 ) displayed increased UV-Vis absorbance due to the quantum confinement effect of the nanofiller, and both the starch-CdS (Radhakrishnan et al 2007) and starch-CdSe (Božanić et al 2009) nano-biocomposite films showed improved light transparency.…”

“…A higher addition level of nanofiller may result in the agglomeration of nanoparticles Liu et al 2011a;Ma et al 2009;Yu et al 2009;Zheng et al 2009a), which is unfavorable for the performance improvement of the nano-biocomposites. In a study on the starch-SiO 2 nanobiocomposites for textile applications, for example, Wu et al (2009b) found that the best tensile strength and wear resistance could be achieved when the nano-SiO 2 addition level was 4 % and 3 %, respectively, with the reasons being the even distribution of the nanoparticles and the strong nanofiller-matrix interactions at these levels, while the lubricating effect of the rigid nanofiller could also contribute to improved abrasion resistance.…”

“…For the nanoparticle synthesis in the second method, polysaccharides such as native starch (Rodriguez et al 2008), soluble starch (Chairam et al 2009;Li et al 2007;Ma et al 2009;Radhakrishnan et al 2007;Vigneshwaran et al 2006;Wei et al 2004), and CMC Liu et al 2011a;Yu et al 2009;Zheng et al 2009a) have been shown to be good stabilizers. Polysaccharides can form complexes with divalent metal ions due to their high number of coordinating functional groups (hydroxyl and glucoside groups) (Taubert and Wegner 2002) and present dynamic supramolecular associations facilitated by inter-and intramolecular hydrogen bonding, which can act as templates for metal nanoparticle growth (Raveendran et al 2003).…”

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.

Nanostructured lanthanum (III)-oxide (La 2 O 3 ) particles were prepared by a polymer complex solution method and further used for the preparation of lanthanum hydroxide (La(OH) 3 ) nanoparticles. The La(OH) 3 nanopowder was mixed with glycerolplasticized maize starch and the effect of the filler on the thermal, mechanical, and viscoelastic properties of the matrix was investigated. It was expected that this nanofiller, which shows an affinity toward OH groups, would strongly affect the physical properties of thermoplastic starch (TPS). The pure TPS and the TPS-La(OH) 3 nanocomposite films (with 1, 2, and 3 wt % filler) were conditioned at various relative humidities (RHs) (35, 57, 75, and 99% RH). After conditioning at 99% RH, the pure TPS films exhibited higher affinity toward water than the nanocomposites. Differential scanning calorimetric measurements showed that, due to retrogradation effects, the melting enthalpies of the films increased with increasing RH. Dynamic mechanical analysis revealed that the mechanical properties in the linear range strongly depend on both the humidity conditions and the concentration of the filler. The results also show that La(OH) 3 nanoparticles are good reinforcement for TPS films.

In this work, new ways to reinforce the performance of starch by incorporating nano-diamond (ND) and chitosan-grafted MWNTs (MWNTs-CS) are developed. The composites are characterized by tensile properties, dispersion properties, thermal analysis, fourier transform infrared (FT-IR), X-ray diffractions (XRD) studies, and water vapor permeability (WVP) tests. Loading of ND not only improves the solubility, but also increases the tensile strength, elongation at break and Young's modulus of the starch composite films, which increases by 235.82%, 78.98%, and 976.51%, respectively. In particular, the synergy effects of Young's modulus achieves the effect of "1 + 1 > 2" which may be attributed to the fact that ND can be adsorbed on the surface of MWNTs by -interactions, which prevents aggregation of MWNTs. Meanwhile, hydrogen bonds between grafted CS and the starch matrix are responsible for generating effective load transfer between ND/MWNTs-CS and the starch matrix, resulting in the simultaneously increased strength and toughness of the nanocomposites. Furthermore, composite film containing ND and MWNTs-CS shows the lowest water vapor permeability among the composite films prepared in this study.
