Abstract
A novel polymer-coated carbon, metal, or ceramic substrate is coated with an aromatic polysiloxane liquid coating solution polymerized to have non-linear, ladder silicon to oxygen bonding. A carbon, metal, or ceramic layer or substrate coated with the aromatic polysiloxane liquid polymer provides enhanced thermal protection and oxidative stability. The novel aromatic polysiloxane liquid polymer-coated carbon, metal, or ceramic substrate preferably includes a non-linear, ladder aromatic polysiloxane polymer-coated carbon, metal, or ceramic substrate such as provided by polyphenylsiloxane polymer having the general formula R.sub.n SiO.sub.(4-n)/2, wherein R comprises phenyl radical, and n has an average value of about 0.95 to 1.05.
