A polymer blend is a macroscopically homogeneous mixture of two or more polymers (homopolymers or copolymers) that have been blended together to create a new material with different physical properties. These blends are intensively studied because of their theoretical and practical importance. They are utilized in various applications, and it has been estimated that approximately 30% of all polymers are sold as a type of polymer blend material. Polymer blends have gained importance because of the ability to modify their mechanical properties (e.g., rubber toughening), but also to adapt properties for other specific applications (e.g., applications of biopolymers in food packaging). The past several decades have seen many developments in the science and engineering of polymer blends. In this Special Issue, we aim to publish full research papers, short communications, and review articles describing the current trends and technologies for the synthesis, modification, and processing of polymer blends. The submissions will focus on improving polymer blend properties and expanding the possibilities for application.
