Synthesis of a novel COF and its composite with PPY during cyclic voltammetric electropolymerization to prepare a new thin film microextraction device

The facile fabrication of the PPY@COF-LU2-based TFME device demonstrates the feasibility of the in-situ CV electropolymerization strategy for preparing COF-polymer composites. This opens a new avenue for cost-effective fabrication of diverse microextraction devices incorporating various COFs and conductive polymers, with broad potential for analytical chemistry applications.
