摘要

Composite materials sonogel-carbon-conductive polymers and their variants: manufacturing process and its application in the constitution of electrochemical sensors (bio) devices. # For the first time a massive composite material based on sonogel, carbon and conductive polymer is synthesized, using ultrasound high energy The design of experiments allows establishing the most appropriate parameters for synthesis. The process is very versatile and generates multiple materials varying the carbon source, catalyst or conductive polymer. These materials can be used to manufacture (bio) electrochemical sensors. # Other advantages of the system are: # - Speed and simplicity of the process and instruments used. # - The polymer is a structural part of the material, increasing its conductivity (91% by weight) and stability with respect to other ceramic materials, influencing the efficiency of the constituted sensor. # - The good mechanical and electrochemical renewal of the material allows a continuous use of these devices, solving the problems of degradation of conductive polymer films in sensors.
