Dominic and Alexander publish a joint paper in Electrochimica Acta on extended DRT analysis of SPEs

In a joint research work within BayBATT, we published detailed DRT analysis of Nyquist plots obtained from Electrochemical Impedance Spectroscopy of solid electrolytes to understand the bulk as well as interface impedance as a function of the nature of electrolytes varying from single-ion conductor polymer to polymer bottle brushes and ceramic electrolytes, all of which are interesting candidates for a solvent-free Li-metal anode battery

Mahima published a perspectives in Macromolecules on Polymer Thermoelectrics

In a perspective article in Macromolecules, the challenges and opportunities of polymeric thermoelectrics for medium temperature and low power regime applications are reviewed. The main focus lies in the interconnectivities of the important TE parameters, Seebeck coefficient, thermal conductivity as well as electrical conductivity and how to improve both S and sigma simultaneously. A paradigm shift towards efficient doping at low dopant levels and separation of transport and fermi energy levels are strongly recommended.

Philip published two important papers for his cumlative PhD disertation

Philip Schmode studied the concept of copolymerization as well as polar polythiophenes carrying oligoethyleneglycol substituents to obtain Ionic Electronic Mixed Conductors for applications in Organic Electrochemical Transistors. The corelation between chemical structures, volumetric capacitance, charge carrier mobility and µC* product are evluated in two papers published in Chem. Mater. (2019) and ACS AMI (2020).

Mukundan ThelakkatWelcome to Applied Functional Polymers group at University of Bayreuth!

We are an interdisciplinary group covering fields of Chemistry, Physics and Material Science.

Our objectives are

  • to design and develop novel tailor made functional molecules, polymers and block copolymers,
  • to combine organics with other functional inorganics to get hybrid systems and
  • to contribute conceptually to solar energy conversion and storage.

Our tools include diverse thin film preparation techniques, self-assembly and device preparation and characterization in addition to elaborate synthetic methods.
