The conference on multi-component polymer alloys, featuring Dr. Rovati from Ecole Polytechnique de Montreal, was held at Qom University of Technology.
According to the university's public relations: Thanks to the Polymer Engineering Group and the cooperation of the Polymer Scientific Association, the conference on multi-component polymer alloys was held with Dr. Rovati from Ecole Polytechnique de Montreal on Wednesday, 30/7/93, in the Shahid Akoundi Conference Hall at Qom University of Technology.
In his lecture, Dr. Rovati discussed the control of morphology in polymer alloys. He added that controlling morphology in polymer alloys has a significant impact on improving the properties of the constituent components of the alloy. He further specified that three factors—thermodynamics, rheology, and concentration—can be considered as determining parameters for the morphology of multi-component polymer alloys. Although the simplest morphologies pertain to binary alloys, including co-continuous and matrix-dispersed phase morphologies, ternary alloys serve as the basis for classifying multi-component mixtures. The science of thermodynamics categorizes ternary alloys morphologically into two types: partial wetting and complete wetting. Utilizing these two categories allows for the creation of specific structures for special applications in multi-component alloys.
Dr. Rovati added that, for instance, the double percolated morphology is created using the complete wetting methodology and is employed in producing materials that require a polymer network with low material concentration. One such material is a blend of polymers and conducting polymer with a double percolated morphology, in which a small amount of conducting polymer (for example, polyaniline) is used to create a network of this polymer throughout the material, resulting in a strong semiconductor blend.
