Chemical features mechanical coupling

The reversibility of the reaction is another important feature of coupling by silanes, titanates, and zirconates. The bond formed in the second stage (see chemical reaction above) is not a permanent bond but is an equilibrium reaction which depends on the amount of water in the system. This is the most important concept in the coupling mechanism. Bonds can form, break, and reform. Water immersion affects the interface, causing bond breakage. Bonds can be reformed again if the internal stress in the polymer matrix does not cause permanent delamination which separates the surfaces. 

Voltammetric features of adsorption coupled EC mechanisms (2.177) [128] and (2.178) [129] are rather unpredictable and deviate strongly from the EQ mechanism of a dissolved redox couple. Their voltammetric behaviour is mainly controlled by the adsorption parameter p, and the dimensionless chemical parameters k"s = j and... 

Poly(dimethylsiloxane) was the backbone of this growing industry. The unprecedented inertness of this polymer under thermal, chemical, and biological environments, coupled with its unique physical behavior, led to a myriad of commercial applications. Its uses include mechanical applications, in which stability in hostile environments was the desired attribute surface treatments, in which low surface energy was the important feature and cosmetic and biomedical applications, in which the biological inertness of the material was exploited. During this period, this new and healthy industry was expanding in all directions.
