摘要：

This study is based on the synthesis of composite particles made of polymer matrix and of intrinsically conducting polymer (ICP), with architecture control. Particle dispersion has been deposited on glass or plastic substrate to form a conducting film. This film has been successfully tested in sensor devices, namely gas sensors and electro-controlled delivery systems. In the first application, films have been performed and tested as active layer for ammonia detection. This chemical sensor template has been optimized in term of chemical composition and properties. These new sensors are sensitive (a pollution as low as 10 ppm ammonia is detected), exhibit a short response time (few seconds) and may be used several times in a row with the same performances. In the second application, core-shell particles have been entrapped into a hydrogel and these hydrogel composites have been characterized by polymerization kinetics, morphological, rheological, and swelling studies. These composites have been then evaluated as potentially drug release templates under electric field.
