Abstract
The recently introduced method of twin polymerization is a synthesis route to produce nanoporous hybrid materials, containing organic and inorganic structure domains of 0.5 to 3 nm in a large variety of different compositions. Although first theoretical and experimental investigation has been performed, the open question still remains: How does the structure formation process of twin polymerization, yielding these interweaved organic-inorganic nanoporous hybrid materials, takes place in detail? Understanding the occurring effects and processes of the structure formation opens up the possibility to design (organic and/or inorganic) nanoporous materials with desired properties for industry. E.g. nanoporous materials are of great interest in applications like gas filter systems, catalyst or fuel cells. Here, we present a possibility to derive kinetic reaction parameters as the activation energy barrier or the reaction rate constant by fitting differential scanning calorimetry data via an equation system obtained from reaction kinetics.
