“…Thus, PHBV presents low crystallization rates as compared to the time scale of most industrial moulding and fabrication process 2 . PHB and PHBV nanocomposites filled with layered clay such as montmorillonite, sepiolita and hectorite have been studied [2][3][4][5][6][7] . It was observed that the incorporation of clay to the polymeric matrix improves mechanical behaviour, thermal properties, gas barrier properties and biodegradation rates of the material as compared to neat polymer.…”

Poly(3-hydroxybutyrate-co-3-hydroxyvalerate) -PHBV is a biodegradable polyester which has been studied as an option for the production of disposable goods. Attapulgite is a fibrous clay mineral. The aim of this work was to produce and characterize renewable resource derived-nanocomposites based on PHBV and organophilic attapulgite (MAT). The nanocomposites were characterized by XRD, SEM and thermal analysis. It was observed reduction in degree of crystallinity, in melting and glass transition temperatures and in thermal stability of polymer due to the addition of clay to PHBV matrix. The best results were obtained for PHBV films containing 3 and 5% MAT. These films presented a slight increase in processing window and decrease in crystalline temperature and in degree of crystallinity as compared to pure PHBV.

“…PCNs show significant improvement in properties when compared with neat polymer and polymers containing micron-sized fillers. Several studies have reported that PCNs show improvement in mechanical properties (Okada et al 1990;Giannelis 1996;Chen et al 2002;Maity et al 2002;Lim et al 2003;Ma et al 2003;Park et al 2003;Pramanik et al 2003;Pramoda et al 2003), a decrease in gas permeability (Yano et al 1993;Messersmith & Giannelis 1995;Bharadwaj 2001;Xu et al 2001) and flammability (Gilman et al 1997(Gilman et al , 2000Gilman 1999) and also affect the biodegradability of biodegradable polymers (Ray et al 2002). There has also been considerable interest in modelling and in the simulation and development of new theories for PCNs.…”

Sodium montmorillonite (Na-MMT) clay was modified with three different unnatural amino acids in order to design intercalated clay structures that may be used for bone biomaterials applications. Prior work on polymer-clay nanocomposites (PCNs) has indicated the effect of the appropriate choice of modifiers on enhancing properties of PCNs. Our X-ray diffraction results indicate an increase in the d-spacing of Na-MMT clay after it was modified with the three unnatural amino acids. Transmission Fourier transform infrared spectroscopy experiments were carried out on the unmodified and modified MMT clay samples to study the molecular interactions between the amino acids used as modifiers and the Na-MMT clay. Cell culture experiments showed that the Na-MMT clay modified with the three amino acids was biocompatible as were the modified clay-incorporated films of chitosan/polygalacturonic acid/hydroxyapatite.
