“…On the other hand, only few works have dealt with the preparation, characterization, crystallization, and properties of PHB‐based polymer nanocomposites 16–20. The nanofillers used for the preparation of PHB‐based nanocomposites are clay and carbon nanotubes.…”

“…The crystallization of PHB is accelerated in the nanocomposites because clay particles act as a strong nucleating agent. The exciting characteristic of PHB/clay nanocomposites is that the rate of biodegradation of PHB is enhanced dramatically in the nanohybrids with respect to neat polymer 16–19. Carbon nanotubes (CNTs) were first reported by Iijima in 1991,20 and the first polymer/CNTs nanocomposites were reported in 1994 21.…”

Biodegradable poly(3‐hydroxybutyrate) (PHB)/functionalized multi‐walled carbon nanotubes (f‐MWNTs) nanocomposite was prepared in this work by solution casting method at 2 wt% f‐MWNTs loading. Scanning electron microscopy and transmission electron microscopy observations indicate a homogeneous distribution of f‐MWNTs in the PHB matrix. Nonisothermal melt crystallization, overall isothermal melt crystallization kinetics, and crystalline morphology of neat PHB and the PHB/f‐MWNTs nanocomposite were studied in detail. It is found that the presence of f‐MWNTs enhances the crystallization of PHB during nonisothermal and isothermal melt crystallization processes in the nanocomposite due to the heterogeneous nucleation effect of f‐MWNTs. Moreover, the incorporation of a small quantity of f‐MWNTs apparently improves the thermal stability of the PHB/f‐MWNTs nanocomposite with respect to neat PHB. Two methods are employed to study the activation energies of thermal degradation for both the neat PHB and the PHB/f‐MWNTs nanocomposite. The activation energy of thermal degradation of the PHB/f‐MWNTs nanocomposite is higher than that of neat PHB. Copyright © 2009 John Wiley & Sons, Ltd.

“…Blending as a technique for raising the thermal stability of PHAs has been reported 133 .

The environmental impact of plastic usage is of critical concern and too great to repair. A shift toward biodegradable food packaging is one option. The aim of this review paper is the study of the potential of biodegradable materials for food packaging. The main characteristics in relation to food usage can be narrowed down to mass transfer (gas and water vapor), thermal and mechanical properties. Among several kinds of biodegradable polymers, poly(hydroxyalkanoate) is one of the favorable candidates for food packaging due to its physical and mechanical properties, biodegradability, with low permeability for O 2 , H 2 O and CO 2 without residues of catalysts and water solubility. The main focus of this article is to address poly(hydroxyalkanoate) as a potential candidate for food packaging. The need of applying biobased polymers in food packaging is presented in the introduction of this study. We also describe the most common biopolymers providing a brief overview of classification and application. This is followed by an outline of biopolymer production and a main section in which the properties of poly(hydroxybutyrate)-based nanocomposites of greatest relevance to food packaging are discussed. Furthermore, several approaches for improvement of poly(hydroxybutyrate) properties are described and the role of nanotechnology to improve its mechanical properties is presented. Finally, the article concludes with a summary as well as some possible future trends.

“…Moreover, it has also been reported that PHAenhanced degradation can be caused by decomposition products of clay organo-modifi ers, which have a catalyzing effect on the thermal or thermomechanical degradation. 55 Lim et al 86 carried out another study on PHB-based nanocomposites with PHB/MMT-Alk4. XRD and infrared spectroscopy data showed evidence of intercalated structures.…”
