| Abstract |
Signal amplification is an efficient method to bring about macroscopic changes of materials, which can be initiated by small concentrations of an analyte. This presentation demonstrates polymeric materials capable of showing amplified responses via (i) self-propagation or (ii) head-to-tail depolymerization. Both reaction mechanisms establish dramatic changes of materials in response to trace, specific stimuli. In particular, self-propagation reaction induces a global change in physical properties of a whole material from a local, fleeting signal; continuous depolymerization reaction provides amplified de-bonding reactions in polymer adhesives once exposed to a trace, chemical signal. |
