Transient Current Responses of Organic Electrochemical Transistors: Evaluating Ion Diffusion, Chemical Capacitance, and Series Elements

Advanced Functional Materials, EarlyView.
This work establishes a general theory of the current transient of ionic‐electronic transistors under a step of gate voltage. The dominant effect is a transient charging of the channel by diffusion of ions. The additional influence of electrolyte capacitance and resistance splits the fundamental time constant of diffusion into two different components.

Wetting of Surface Grafted Hydrophilic‐b‐Hydrophobic Block Copolymer Brushes

Advanced Functional Materials, EarlyView.
The wetting properties of surface grafted diblock copolymer brushes are influenced by the thickness of the hydrophilic bottom block and the hydrophobic top block. The surface adapts in presence of water and the contact angles of the bottom block shine through. Abstract The wetting of diblock copolymer brushes by water is studied.
