摘要：

Generally, conventional sol-gels are rather hydrophilic and well suited for sensing some ions such as H+. A more hydrophobic material for ammonia sensing ormosils materials can be obtained by preparing organically modified siloxanes ormosils. When dimethyldimethoxysilane (DiMe-DMOS) is mixed with an alkoxide such as tetramethoxysilane (TEOS) in a suitable soluent and catalyst, gels can be prepared which exhibit rubbery elasticity.
