The introduction of a filler and consequent increase in the thermodynamic compatibility of binary polyblends

Strategies for compatibilization of polymer blends

“…[153] It has been reported that the concentration dependence of χ 23 is shifted towards smaller values of χ 23 as the kaolin content is increased. A positive value of χ 23 indicates that the neat PMMA-PBMA pair is completely immiscible in the melt (at 475 K), whatever the PMMA volume fraction.…”

“…General principles -Section 3.9 has shown that the immiscibility of two polymers can be tuned by a third polymer miscible with each of them. Similarly Shifrin et al [153] have proposed an alternative approach that consists of substituting a mineral filler for the third polymer as a compatibilizer for a two-phase polymer blend. The selective localization of the filler at the interface is a prerequisite, which is fulfilled (or not) depending on the balance of interactions between the filler and each constitutive polymer.…”

Thermodynamic stability of colloid polymer-polymer systems

“…Figures 6, 7 and 8 show the dependencies of parameter Z23 on mixture composition at various filler content and at different temperatures for the systems polyethylene-polyurethane and polymethylmethacrylatepolybuthylmethacrylate [29]. It is seen that the PE-PU mixture is incompatible in the melt as parameter Z23 exceeds 0 in the given temperature interval.…”

Mechanical, electrical, and dielectric properties of polyvinylidene fluoride/short carbon fiber composites with low‐electrical percolation threshold

“…It is well documented that electrical, dielectric, mechanical or any other physical property of the polymer composites depend on the nature of polymer and filler individually . There are several other factors like filler dispersion in polymer matrix, physicochemical bonding in between polymer and filler, polymer–polymer compatibility in case polymer blend is used as matrix, electronic charactrestis of polymer and filler for example presence of lone pair or pi bond or both in conjugation in polymer, duration of mixing time, method of mixing, aspect ratio of filler, temperature of mixing. All these factors affect the physical properties of polymer–filler composites.…”
