Monte Carlo simulation of the energetics and thermodynamics of polypyrrole in condensed phases

Helmick G., Abere Y., Blaisten-Barojas E., George Mason University, US

Polypyrrole (PPy) is a conducting polymer with a wide range of applications such as supercapacitors, sensors, batteries, actuators, and neural prosthetics. PPy is a popular polymer in experimentation not so easily accessed in computational modeling [...]

All-Solid-State Stretchable Supercapacitors using Polypyrrole-CNT Hybrid Partially Embedded in PDMS

Zhang R., Stevens Institute of Technology, US

Flexible electronics have a wide range of applications in wearable and multifunctional electronics [1], including flexible displays, curved smart phones, electronic skins, and implantable medical devices. Consequently technologies for flexible energy storage have to be [...]

An inkjet printed NO2 sensor operating under room temperature and low humidity environment

Wang W., Su Y-C, Chuang W-Y, Lin C-T, Wu W-J, National Taiwan University, TW

A room temperature operation NO2 sensor base on polypyrrole (PPy) /AZO (5% Al-doped ZnO) sensing material was developed. For the environmental monitoring, the ambient factor effect for NO2 detection was further discussed. Based on the [...]

Conjugated Polymer Papers for Metal Ion Detection

Ahn K-J, Yoon H., Chonnam National University, KR

It is of great importance to detect heavy metal ion in solution. Here, we describe the electrochemical detection of metal ions using polypyrrole/cellulose (PPCL) composite papers in both static and flow systems. A home-made electrochemical [...]

Conductive Ppy-DS/Fe-MMT Layered Nanocomposites

Enomoto H., Kanda R., Lerner M.M., Osaka Electro-Communication University, JP

Conductive polypyrrole/montmorillonite (Ppy/MMT) nanocomposites were synthesized by the in-situ polymerization of Ppy in the gallery of MMT layers. The constrained environment of the interlayer gallery of clay host is expected to serve as a template [...]

Synthesis and characterization of (polypyrrole/carbon) nanotubes/metal oxide composites for application as supercapacitors

de Oliveira A.H.P., de Oliveira H.P., de Oliveira A.H.P., de Oliveira H.P., UNIVASF, BR

The development of eco-friendly technologies such as hybrid vehicles requires more efficient high power energy storage materials, viz. supercapacitors. As reported in our previous work, the association of polypyrrole and carbon derivatives (modified graphene oxide [...]

A Low-Voltage Droplet Manipulation via Tunable Wetting on a Polypyrrole (DBS) Surface

Xu W., Tian Y., Bisaria H., Ahn P., Li X., Tsai Y-T, Choi C-H, Yang E.H., Stevens Institute of Technology, US

Electrowetting on dielectric (EWOD) technique has been used to manipulate microliter-sized individual droplets for microfluidic application. However, EWOD-based techniques typically require relatively high actuation voltages (12-80V), which is undesirable for biomedical applications or the applications [...]

Li X., Maladier-Jugroot C., Royal Military College of Canada, CA

cations (1-2). Polypyrrole is one of the most studied conducting polymers due to its good electrical conductivity, environmental stability and relatively easy synthesis (3-6). Earlier we reported an innovative way of synthesizing polypyrrole within nanotemplates [...]

Droplet actuation in PPy redox process

Tsai Y-T, Choi C-H, Yang E.H., Stevens Institute of Technology, US

A wettability switchable surface will be demonstrated to study the contact angle hysteresis of liquid droplet. Manipulation of surface wettability can be applied in the field of biomedical (cell-surface interaction) and fluids dynamics (friction reduction). [...]
