  1. 1. Electrochemical behavior of conducting polymers

    University essay from KTH/Kemi

    Author : Raghda Kalifa; [2022]
    Keywords : Cathodic protection; conducting polymers; conductivity; structure; compression; Katodiskt skydd; ledande polymerer; konduktivitet; struktur; kompression;

    Abstract : Ett stort industriellt problem när det gäller metalliska material är korrosion. En metod för att förhindra korrosion är genom en elektrokemisk process som kallas katodiskt skydd vilket kan utföras på två olika sätt: Katodiskt korrosionsskydd med påtryckt ström (ICCP) eller offeranod (SACP).

  3. 2. Development and Evaluation of Textile Actuators

    University essay from Linköpings universitet/Biosensorer och bioelektronik

    Author : Fredrik Ekman; [2016]
    Keywords : Conducting Polymer; Textile; Actuator; Soft Robotics;

    Abstract : Existing actuators in robotics are noisy, rigid and not very lifelike in their movements. There is a need for actuators in especially limb prosthetics and exoskeletons that are silent, softly moving and preferably operating on low currents. One such solution is the conducting polymers.

  4. 3. Geometrical and Electronic Structure Characterization of Conducting Hydroquinone Substituted Polypyrrole

    University essay from Uppsala universitet/Materialteori

    Author : Anton Segerkvist; [2016]
    Keywords : ;

    Abstract : The fundamental electronic and geometric structures of charged polypyrrole and a hydroquinone substituted polypyrrole, poly(pyrrol-3-ylhydroquinone), were investigated. A single electron was constrained over different sizes of the polymer chains, a polaron, with the purpose of finding the polaron size which minimizes the excitation energy. READ MORE

  5. 4. Patterning of Highly Conductive Conjugated Polymers for Actuator Fabrication

    University essay from Linköpings universitet/Biosensorer och bioelektronik

    Author : Daniel Falk; [2015]
    Keywords : Biosensors; Bioelectronics; Microactuators; Conjugated polymers; Polypyrrole; PEDOT; Soft Lithography; Microcontact printing; Vapor phase polymerization; Drop-on-Demand printing; Photolithography; Lift-off;

    Abstract : Trilayer polypyrrole microactuators that can operate in air have previously been developed. They consist of two outer layers ofthe electroactive polymer polypyrrole (PPy) and one inner layer of a porous poly(vinylidene flouride) (PVDF) membranecontaining a liquid electrolyte. READ MORE

  6. 5. Synthesis and electrochemical characterisation of processable polypyrrole boronic acid derivatives for carbohydrate binding

    University essay from Linköpings universitet/Biosensorer och bioelektronik; Linköpings universitet/Tekniska fakulteten

    Author : Kalle Bunnfors; [2015]
    Keywords : Conducting polymers; polypyrrole; boronic acid; carbohydrates; reagent-free detection.;

    Abstract : Conducting polymers have been widely explored for many different purposes including sensing. In thisthesis the conducive properties of pyrrole and the carbohydrate binding properties of boronic acid iscombined to make a reagent-free detector for carbohydrates. READ MORE
