  • Electric Double Layer Formed by Polarized Ferroelectric Thin Films

    ACS Applied Materials and Interfaces

    Ferroelectric surfaces can have very high surface charge densities that can be harnessed for manipulation of charged colloidal particles and soft matter in aqueous environments. Here, we report on the electrical double layer (EDL) formed by polarized ultrasmooth lead zirconium titanate (US-PZT) thin films in dilute electrolyte solutions. Using colloidal probe force microscopy (CPFM) measurements, we show that the ion distribution within the double layer can be changed by reversing the…

    Ferroelectric surfaces can have very high surface charge densities that can be harnessed for manipulation of charged colloidal particles and soft matter in aqueous environments. Here, we report on the electrical double layer (EDL) formed by polarized ultrasmooth lead zirconium titanate (US-PZT) thin films in dilute electrolyte solutions. Using colloidal probe force microscopy (CPFM) measurements, we show that the ion distribution within the double layer can be changed by reversing the ferroelectric polarization state of US-PZT. The interaction force in dilute 1:1 electrolyte solution between the negatively charged probe and a positive surface charge (upward polarized) US-PZT thin film is attractive, while the interaction force is repulsive for a negative surface charge (downward polarized) film. We modeled these interactions with a constant-potential EDL model between dissimilar surfaces with the inclusion of a Stern layer. We report the surface potentials at the inner and outer-Helmholtz planes both for polarization states and for a range of ionic strength solutions. Effects of free-charge carriers, limitations of the analytical model, and effects of surface roughness are discussed.

  • Stimulus-responsive polymer brushes on surfaces: Transduction mechanisms and applications

    Progress in Polymer Science

    Stimulus-responsive polymer brushes (SRPBs) exhibit a change in conformation and structure, often accompanied by a noticeable change in surface energy, due to an external stimulus such as a change in solvent composition, temperature, pH, ionic strength, light, or mechanical stress. SRPBs offer exciting and new possibilities to fabricate adaptive or responsive smart materials. This review summarizes selected, recent progress in SRPB applications in the field of surface wettability switching…

SRPBs offer exciting and new possibilities to fabricate adaptive or responsive smart materials. This review summarizes selected, recent progress in SRPB applications in the field of surface wettability switching, mechanical actuation, and environmental sensing. Furthermore, we review selected papers from an emerging area in which SRPBs are used for nano- and microfabrication.

  • Ferroelectric Thin Films in Fluidic Environments: A New Interface for Sensing and Manipulation of Matter

    Small

    For decades ferroelectric thin films (FETFs) have been the focus of research and development for next-generation memory and semiconductor devices. FETFs are attractive because their polarization states are highly localized, stable, and switchable. These unique properties are also attractive for (bio)molecular sensing and separation applications. Polarization of both polymer and ceramic FETF results in the expression of a sustained high, non-Faradaic, surface charge density. If these surface…

    For decades ferroelectric thin films (FETFs) have been the focus of research and development for next-generation memory and semiconductor devices. FETFs are attractive because their polarization states are highly localized, stable, and switchable. These unique properties are also attractive for (bio)molecular sensing and separation applications. Polarization of both polymer and ceramic FETF results in the expression of a sustained high, non-Faradaic, surface charge density. If these surface charges are maintained in aqueous environments, then the resulting electrostatic forces should induce the formation of electrolyte gradients and aid in the localization of charged species to the surface. Recently, there has been a growing interest in the interfacial properties of FETFs, specifically how they interact with liquid or gaseous phases. Recent work has shown that the FETF polarization state affects adsorption from the gaseous phase, surface catalysis, and cell growth. Encouraged by these findings, the use of FETFs in aqueous environments is explored. After an introduction to FETFs, the growing body of literature on the FETF interface is reviewed, along with the limited number of studies demonstrating FETF function in gas and liquid environments. Finally, the exciting possibilities that FETFs could bring to interfacial engineering and lab-on-chip (LOC) device design is reviewed.

  • Field‐Induced Nanolithography for Patterning of Non‐Fouling Polymer Brush Surfaces

    Small

    Electric-field induced nanolithography (FINL) on four hydrophilic polymer brushes is demonstrated. FINL is a nanoscale surface patterning method that depends on an electrochemical reaction at the tip–brush interface. FINL feature size depends on the applied bias, relative humidity, and exposure time. FINL patterning yields electrochemically modified brush surfaces that can be used to attach diagnostically relevant probes.
