Polymers in interface-dominated geometries: Structure, dynamics and function in planar and in porous hybrid systems (Project B7 of SFB 986)

           

 

This project focuses on investigations of Polypyrol (PPy) inside tubular pores in a micro-, meso-, and macro-porous Silicon (PSi). PPy offers the possibility to modify the electrical conductivity of PSi in a controlled way. It furthermore opens up sensoric and actoric applications for the PPy/PSi hybrid system. The experiments with the 1D system will be complemented by investigations in the planar 2D geometry. This combined approach permits to establish PPy/PSi as a multiscale hybrid model system within the SFB 986, and at the same time it opens up application-oriented developments.

  • 12.09.2024 Article "Deformation dynamics of nanopores upon water imbibition" published in PNAS

    Our article shows by a combination of experiments and computer simulations of water imbibition in nanopores that the competition between expansive, surface stress release at pore walls and negative, contractile Laplace pressures of nanoscale menisci lead to an unusual macroscopic behavior of the porous medium, which is generic for any liquid/nanoporous solid combination. The results allow one to quantify surface and Laplace stresses and to monitor nanoscale flow and infiltration states by relatively simple length measurements of the porous medium.
