“…It is expected that the surface energy of the filler, whose value is between the values of blend constituents, will result in the effective adhesion at the interface and consequently in the improved morphology 18–20,23. When the stearate‐pretreated filler is added to SAN/EPDM blends, it is expected that the morphology of blends will become finer in comparison to the blends without filler 24, 25. This behavior is in accordance with SEM results (Fig.…”

The properties of styrene–acrylonitrile (SAN) and ethylene–propylene–diene (EPDM) blends containing different types of calcium carbonate filler were studied. The influence of mixing type process on the blend properties was also studied. Two different mixing processes were used. The first one includes mixing of all components together. The other process is a two‐step mixing procedure: masterbatch (MB; EPDM/SAN/filler blend) was prepared and then it was mixed with previously prepared polymer blend. Surface energy of samples was determined to predict the strength of interactions between polymer blend components and used fillers. The phase morphology of blends and their thermal and mechanical properties were studied. From the results, it can be concluded that the type of mixing process has a strong influence on the morphological, thermal, and mechanical properties of blends. The two‐step mixing process causes better dispersion of fillers in blends as well as better dispersion of EPDM in SAN matrix, and therefore, the finest morphology and improved properties are observed in blends with MB. It can be concluded that the type of mixing process and carefully chosen compatibilizer are the important factors for obtaining the improved compatibility of SAN/EPDM blends. © 2012 Wiley Periodicals, Inc.

A novel method for designing hydrophobicity of the polylactide/low‐density polyethylene (PLA/PE‐LD) blends by creating specific surface topography is proposed. In order to increase hydrophobicity by changing the topography of two‐phase PLA polymer blend surface, blends are etched by using ICP before the fluorocarbon‐based coating treatment done in the second step. During the surface treatment process PLA is etched significantly more than PE‐LD and specific “island‐like” surface morphology is created. It has small pillars, 15 µm wide and approximately 125 µm away from each other, which after the fluorocarbon‐based treatment has very high contact angle (>120°). Without the etching, due to smooth surface, PLA/PE‐LD 90/10 polymer blend contact angle is between 100° and 110°.

This article describes the use of commercial silica (SiO 2 ) and calcium carbonate (CaCO 3 ) nanofillers as compatibilizers in immiscible polylactide/low-density polyethylene (PLA/LDPE) blends. The general aim of the study was to investigate the possibilities of replacing standard commodity plastics such as LDPE based on non-renewable mineral oil resources with the biodegradable renewable polymer PLA in compatibilized PLA/LDPE blends for use in the packaging industry. The calculations of the minimal interfacial energy and optimal wetting abilities indicated that SiO 2 filler was a better potential compatibilizer than CaCO 3 for a given PLA/ LDPE blend. This was due to its preferential localization at the interface. The significantly improved morphology of the ternary PLA/ LDPE/SiO 2 blend was found to present an increased strength, toughness, and crystallinity.
