| Abstract Scope |
Poly(carborane-siloxane-(aryl)acetylene)s or PCSA(A)s have been extensively developed in the author’s lab and they provide a platform for advanced functional materials development that is unmatched by a single group of polymers. Myriad applications include their utility as thermal (TBCs) and environmental (EBCs) barrier coatings for polymer matrix composites (PMCs) and for electrically insulating polymers such as polyimides, whereby insulative and thermo-oxidative protections are imparted to the adherent substrate. PCSA(A)s have rheological properties that are optimal for infusion processes facilitating processing of ceramic matrix composites (CMCs). Furthermore, in combination with ultrahigh temperature ceramics, they can provide improved electromagnetic wave-absorbing composites for advanced aerospace and electronic applications. Also, the three distinct functional components, i.e. carborane, siloxane and aromatic carbon, afford them an ability to form products spanning inorganic, organic, polymer, ceramic and metallic regimes. New ML/AI approaches to further catalyze the development of these versatile polymers and their derivatives will also be discussed. |
