“…It seems that this hypothesis is too strong. More and more studies [9,10,[14][15][16][17][18][19][20][21][22][23][24][25][26][27][28] are showing large domains of co-continuity rather than a single composition. The range of compositions in which dual phase continuity can occur seems to depend strongly on the mixing conditions.…”

Blends of polystyrene and high-density or linear low-density polyethylene have been prepared in an internal mixer and studied in a wide range of compositions. Phase inversion compositions have been determined using selective extraction and scanning electron microscopy. It appears that phase inversion can occur in a domain of compositions rather than at a single point. The existing models of phase inversion are not complete enough to explain the entire phenomenon, and percolation of each component may be considered to describe the formation of co-continuity.

“…4(b) and (c) shows EDS compositional mapping of the carbon and nitrogen elements, respectively. Image analysis has been suggested for interfacial area and morphology detection in polymer blends (Galloway et al, 2002). In this work, to obtain obvious images of the blend morphology, ImageJ software is used and the process of applying this software for nitrogen (a constituent element of NBR) mapping of the 80/0/0 sample is illustrated in Fig.…”

“…Therefore, it is important to perform accurate determination of the co-continuous phase morphology to verify the occurrence of thermoplastic elastomer materials based on rubber and plastic blends. A variety of methods have been used to determine co-continuity including microscopy, solvent extraction, rheological measurements and electrical conductivity [7][8][9][10][11].…”

Abstract:Blending of polymers provide an attractive route to obtain new materials with unique combination of properties. Among the possible blend morphologies are dispersion of droplet, fiber, lamella in continuous phase and cocontinuous morphology. The unique feature of co-continuous is the mutual interpenetration of the phases which exhibits a number of advantageous properties and hence wider range of applications. Therefore, it is important to perform accurate determination of the co-continuous phase morphology and phase inversion phenomena. The rubber co-continuity index (solvent extraction), SEM micrographs and dynamic properties indicated the inversion occurred in the blends with rubber content 40 to 50 wt%. Furthermore, three empirical models (i.e., Ultracki, Steiman et al and Gergen et al models) could predict the phase continuity and phase inversion phenomena but other two (i.e., Paul-Barlow and MetelkinBlekht models) failed. Therefore, based on rubber co-continuity index, SEM micrographs, dynamic mechanical properties and prediction, the inversion phenomena occurred in the blends with rubber contents in a range of 40-50 wt%. Full co-continuity was found in the blends with the rubber contents of 46 to 60 wt%.
