SU8-graphene: a new photo-patternable conductive polymer composite

Majidian M., Grimaldi C., Baibarac M., Baltog I., Forró L., Magrez A., EPFL, CH

SU8 epoxy is a photo-resist with great intrinsic properties such as high thermal stability, chemical and mechanical robustness along with high sensitivity to UV. Having eight reactive epoxy sites in each monomer molecule, a high [...]

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 [...]

Resistance and Potentiostatic Based Measurements of an Antibody Functionalized Conductive Polymer Coated Textile as a Biosensor

Bandremer A., Hebert A., Torosian S.D., Battacharyya D., Gleason K., McGraw S.K., Senecal A., Marek P., Food and Drug Administration, US

Effective food safety monitoring is challenged by the necessity to identify human infection capable microorganisms at sufficient infective doses and consumption levels. Regulatory agencies have developed methods for assessing food safety based on currently available [...]

Conductive Polymer Microelectrodes for on-chip measurement of transmitter release from living cells

Tylsgaard Larsen S., Matteucci M., Taboryski R., Technical University of Denmark, DK

In this work we present an all-polymer chip for measuring exocytotic release from neuronal cells using electrochemical sensing at a conductive polymer microelectrode. This chip combines several novel aspects, such as the use of conductive [...]

Highly conductive nanotube-filled polymers with exceptional properties

Tiano T., Czerw R., Coffin R., Adams R., NanoTechLabs Inc., US

NanoTechLabs has developed new methods for preparation of highly conductive high-performance polymers. We use novel, scalable methods to incorporate high aspect ratio, low diameter, metallic multi-wall nanotubes (MWNT) into high performance engineering resins and plastics. [...]

Preparation of nickel doped multi-functional micro-patternable polydimethylsiloxane nanocomposite polymer with characterization of its magnetic, electrical and mechanical properties for soft MEMS/Lab on a chip applications

Khosla A., Korand J.L., Haiducu M., Gray B.L., Leznoff D.B., Parameswaran M., Simon Fraser University, CA

We present the preparation and characterization of a novel polydimethylsiloxane (PDMS) multifunctional nanocomposite with electric and magnetic properties. The composite is fabricated by ultrasonic agitation of nickel nanoparticles in the PDMS matrix. The prepared nanocomposite [...]

Low-Energy, Solventless Coating Processes

Lewis H.P., GVD Corporation, US

GVD Corporation is commercializing solvent-free, chemically-pure polymer coatings formed by chemical vapor deposition (CVD). GVD’s all-dry coatings currently range from fluorocarbons to silicones to electrically-conductive polymers. These novel coatings are deposited from the vapor phase, [...]

Quantum Dots/Conductive Polymer Nanocomposite

Chen C-M, Chen H-S, Huang H-C, Chen C-M, Chen H-S, ITRI, TW

The nanocomposite composed of CdSe quantum dots and conductive polymer (MDMO-PPV) was investigated. The spherical 3.8-nm functionalized CdSe quantum dots were synthesized by colloidal chemical method. The conductive polymer MDMO-PPV was synthesized from 1-methoxyl-4-(3,7dimethyl-octanoxyl)benzene and [...]
