“…The morphology of the polymer blend plays a critical role in understanding the structure-property relationships between the blend components, and hence there has been much research on structure development in such blends. Several studies were conducted on evaluating the morphology of PCL/PBS blends by employing scanning electron microscopy (SEM) and polarized light optical microscopy (PLOM) [16,17,[19][20][21]27]. These blends were mostly prepared through melt blending and solution mixing methods.…”

“…Although blending is a good method for improving the properties of the individual polymers, the PCL/PBS blends are immiscible as evidenced by composition independent T g s and a bi phasic melt, which leads to poor interfacial adhesion and macrophase separation. Several methods, such as the addition of the copolymers (poly (ethylene oxide)-block-poly(propylene oxide)-blockpoly(ethylene oxide) (PEO-PPO-PEO) and poly(butylene succinate-co-ɛ-caprolactone) (P(BS-co-CL)) and thermoplastic soy meal (TSM), have been applied to improve miscibility, interfacial adhesion and the resultant mechanical properties of PCL/PBS blends [16,20,21]. Recent reports [37][38][39] revealed that adding conductive carbon-based nano-fillers such as carbon nanotubes (CNTs) into PCL and PBS matrices can enhance some of the matrix properties to better levels than those of the copolymers or polymers filled with metal powders, as well as produce electrically conductive materials with better mechanical properties.…”

“…Additionally, a wide range of material properties is within reach by merely changing the blend composition [11]. PCL was blended with various other biodegradable polymers in a number of studies [12][13][14][15][16][17][18][19][20][21][22]. Amongst various biodegradable polymers, PBS was the most interesting aliphatic polyester due to its relatively good melt processability, thermal and chemical resistance, biodegradability, and excellent mechanical properties, closely comparable to those of the widely-used polyethylene (PE) and polypropylene (PP) [4,5,[15][16][17][18][19][20][21][23][24][25][26][27][28][29][30][31][32][33][34][35][36].…”

Abstract. Biodegradable polymers received considerable attention due to their contribution in the reduction of environmental concerns and the realization that global petroleum resources are finite. The development of double crystalline biobased blends such as poly(ε-caprolactone) (PCL) and poly(butylene succinate) (PBS) are particularly interesting because each component has an influence on the crystallization behaviour of the other component, and thus influences the strength and mechanical properties of a polymer blend. The lack of miscibility between PCL and PBS constitutes a bottleneck, and efforts have been made to improve the miscibility through the inclusion of copolymers. Having realized that incorporating conductive nanofillers such as carbon nanotubes (CNTs), (especially when the CNTs are functionalized or used as a masterbatch i.e., polycarbonate/MWCNTs masterbatch), into biopolymer matrices, can enhance the thermal and mechanical properties, as well as electrical and thermal conductivity, a lot of research was aimed at the production of bionanocomposites. This review paper discusses the properties of PCL, PBS, their blends, and their CNTs containing nanocomposites.

As alternatives to petroleum-based polymeric materials, biodegradable polymers, such as polycaprolactone has attracted a lot of attention in the scientific community due to a rapid growth of intensive interest in the global environment. Chalcone, hexadecylamine and tetradecylamine were used as one of the organic compounds to modify natural montmorillonite clay. The clay modification was carried out by stirring the clay particles in an aqueous solution of chalcone-montmorillonite, hexadecylamine-montmorillonite and tetradecylamine-montmorillonite increasing from 1.29 to 1.53, 1.59 and 1.79 nm, respectively. The modified clay was then used in the preparation of the polycaprolactone/epoxidized palm oil blend nanocomposites. They were prepared by incorporating 0.5-5% of chalcone-montmorillonite, hexadecylamine-montmorillonite and tetradecylaminemontmorillonite. The interaction of the modifier in the clay layer was characterized by X-ray diffraction and transmission electron microscopy. The nanocomposites were synthesized by solution casting of the modified clay and a polycaprolactone/epoxidized palm oil blend at the weight ratio of 80/20, which had the highest increase in the tensile strength of the blend. The X-ray diffraction and transmission electron microscopy results confirmed the production of nanocomposites. The results also showed higher thermal stability for nanocomposites compared to those of the polycaprolactone/ epoxidized palm oil blend.

in this study, epoxidized palm oil (ePo) was employed as a modifier for polybutylene succinate (ePo) using chloroform as a solvent by solution casting process. Fourier transform infrared (Ftir) spectroscopy was used to identify the functional groups of PBs and PBs/ePo blends. thermal stability and morphological properties of the blends were investigated by thermogravimetric analyzer (tGA) and scanning electron microscope (sem) technique, respectively. Biodegradation of this blend was also studied. the Ftir spectra indicated that there are some molecular interactions by intermolecular hydrogen bond between PBs and ePo. the PBs/ePo blend showed high thermal stability and significant improvement of biodegradation compare to pure PBs. morphological results of PBs/ePo blends showed that ePo was good miscible with PBs.
