Abstract Scope |
While strides have been made in understanding processing factors which contribute to ceramic yield and composition made through preceramic polymers, comparatively little is known regarding the impact of minor changes to the polymer backbone. Herein, we examine the impact of chemical connectivity (i.e. the arrangements of elements in polymers with the same empirical chemical formula) on ceramic yield and composition through new preceramic polymers using CuAAC. Zirconium and silicon containing polymers with varied connectivity are investigated, with differences in ceramic yield as large as 10% identified. Additionally, ceramic composition is seen to vary depending on connectivity during and after pyrolysis. |
