“…In some studies (Arroyo et al 2010;Avella et al 2005;Bocchini et al 2010;Dean et al 2008;Majdzadeh-Ardakani and Nazari 2010;McGlashan and Halley 2003), systematic investigations were carried out to find out the effects of the second polymer content, the nanofiller type and content, 2014 and some other parameters on the properties of the nanocomposites and also to find out the optimized applicable products. Nanocomposites based on starch blends are also expected to show improved characteristics such as mechanical properties (increases in the storage modulus (Bocchini et al 2010;Vertuccio et al 2009), Young's modulus (Arroyo et al 2010;Avella et al 2005;Dean et al 2008Dean et al , 2011Ikeo et al 2006;McGlashan and Halley 2003;Mondragón et al 2009;Pérez et al 2007), and tensile strength (Arroyo et al 2010;Avella et al 2005;Dean et al 2008Dean et al , 2011Ikeo et al 2006;McGlashan and Halley 2003;Mondragón et al 2009;Pérez et al 2007)).…”

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.

Our purpose was to improve the thermal, mechanical, and optimal properties of an epoxy bioresin using optimum hybrid natural pigments previously synthetized in our lab. Then, we searched the best combinations of factors in the synthesis of natural hybrid nanopigments, and then incorporated them into the bioresin. We combined three structural modifiers in the nanopigment synthesis, surfactant, coupling agent (silane) and a mordant salt (alum), selected to replicate mordant textile dyeing with natural dyes.We used Taguchi's design L8 to seek final performance optimisation. We selected three natural dyes, chlorophyll, beta-carotene and beetroot extract, and used two laminar nanoclay types, montmorillonite, and hydrotalcite. The thermal, mechanical and colorimetric characterisation of the composite obtained by mixing natural hybrid nanopigments (bionanocomposite) was made. The natural dye interactions with both nanoclays improved the natural dyes and bioresin's thermal stabilities, colour performance and UV-VIS light exposure stability. The best bionanocomposite materials were found by using an acidic pH [3][4] environment, and modifying nanoclays with mordant and surfactant during the nanopigment synthesis process.

“…In this case, a good dispersion of clay within the matrix and an intercalated structure is obtained by using unmodified sodium montmorillonite (Ali et al 2011). Intercalated structures are also obtained by melt blending and compounding of TPS with PCL, PLA, PBSA and PVA and most types of compatibilized clays (Ali et al 2011;Pérez et al 2007;Lee and Hanna 2009;Bocchini et al 2010;Majdzadeh-Ardakani and Nazari 2010). However, there are a few cases where the melt intercalation process resulted into well-exfoliated structures as reported by Perez et al (Pérez et al 2007) who worked with starch/PCL/C30B, Majdzadeh-Ardakani and Nazari (2010) and Dean et al (2008) who prepared starch/PVA/MMT-Na+ nanocomposites, and Bocchini et al (2010) who worked with starch/PBSA/C30B.…”

This chapter is a comprehensive source for biodegradable polymer/clay nanocomposite research. The work focuses on several strategies to obtain well-dispersed nanocomposites with improved mechanical properties. Different strategies for optimization of biodegradable polymer-clay nanocomposites were identified and treated herein. The two most important strategies are based on the chemical modification of the clay and on the processing conditions. The combination of these two factors greatly affects the resulting structure of the nano composite, being always the goal to obtain a good dispersion of the reinforcement within the polymeric matrix. Challenges in processing conditions have been analyzed and the prospective for future research has been addressed.
