“…These blends were mostly prepared through melt blending and solution mixing methods. Regardless of the preparation method used, the morphologies of the blends were found to depend on the ratios of the components in the blend, their viscosities, and the interfacial tension between the component phases [27,48]. Depending on the PCL/PBS blend ratios, the minor component generally formed discrete spherical domains in a matrix of the major component, which indicates poor interfacial interactions between the components.…”

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.

“…of polymer blends has long been a research focus. [1][2][3][4] Basically, there are three kinds of phase structures in ternary systems: (1) the components of the dispersed phases are dispersed separately; (2) one component is encapsulated by another component, forming core-shell particles dispersed in the third phase; (3) in an intermediate state, partial encapsulation of one dispersed component by another one could occur. [4][5][6][7][8][9][10] Hobbs et al [7] showed that the morphology of ternary blends can be predicted through knowledge of the interfacial tension between the components of the blends.…”

In this study, the effect of several parameters, including composition, order of mixing, viscosity, and interfacial tension, on the phase structure and size of dispersed particles of polyamide 6 (PA6)/poly(styrene-co-acrylonitrile) SAN/poly(styrene-b-(ethylene-cobutylene)-b-styrene) (SEBS) ternary blends was investigated. Moreover, the effect of addition of different ratios of reactive SEBS (maleic anhydride grafted-SEBS) and nonreactive SEBS at a fixed order of mixing and composition of 70/15/15 (PA6/SAN/SEBS + SEBS-g-MAH) on the mechanical properties of ternary blends was examined. Scanning electron microscopy (SEM) micrographs showed that among the studied parameters, interfacial tension and viscosity of dispersed phases were the leading factors in the formation of morphology and size of dispersed droplets. Mechanical results revealed that in contrast to the expectation, formation of core/shell structure of PA6/SAN/SEBS ternary blends did not result in a significant increasing of impact strength. The highest impact strength was achieved when a 50/50 weight ratio of SEBS/SEBS-g-MAH was used.

“…1,2 Melt blending of two or more polymers is a collaborative approach to develop new material with customized properties. 3,4 Prediction, control and study of morphology and mechanical properties in polymer blend especially in ternary polymer blend are a difficult task. 5,6 Generally the morphology of a ternary polymer blend is depended on interaction parameters among three components, rheological properties of the components and processing conditions.…”

“…Investigation of ternary polymer blends was first reported in the 1980s by Hobbs et al 3,12,13 In particular, they used the concept of spreading coefficient and rewrote Harkin's equation in which two distinct phases are dispersed in a matrix phase to predict the morphology of ternary blends. In a ternary blend of 폴리머, 제38권 제4호, 2014년 three polymers A, B, and C, the spreading coefficient, λ ijk , can be defined as eq.…”

Ternary blends of poly(L-lactic acid) (PLLA), poly(ε-caprolactone) (PCL) and polyethylene oxide (PEO) were produced with different concentrations of components via melt blending. By leaching the PEO from the samples by water, porous materials were obtained with potential application for bio scaffolds. Sample porosity was evaluated by calculating the ratio of porous scaffold density (ρ*) to the non-porous material density (ρ s ). Highest porosity (51.42%) was related to the samples containing 50 wt%. of PEO. Scanning electron microscopy (SEM) studies showed the best porosity resulted by decreasing PLLA/PCL ratio at constant concentration of PEO. Crystallization behavior of the ternary blend samples was studied using differential scanning calorimetry (DSC). Results revealed that the crystallinity of PLLA was improved by addition of PEO and PCL to the samples. The porosity plays a key role in governing the compression properties. Mechanical properties are presented by Gibson-Ashby model.
