  1. 1. Corrosion protection of aluminum coated with a polymer matrix in presence and absence of conductive polymer

    Master-uppsats, KTH/Ytbehandlingsteknik

    Författare :Mohamed Hassan Abdi; [2021]
    Nyckelord :Corrosion protection; Barrier coating; Conductive polymer; Electrochemical impedance spectroscopy; Atomic force microscopy; Korrosionsskydd; Barriär beläggning; Ledande polymer; Elektrokemisk impedans spektroskopi; Atomkraftmikroskopi;

    Sammanfattning : Aluminium och aluminiumlegeringar har ganska bra korrosionsbeständighet, men dessa material kan fortfarande korrodera. Metallkorrosion är aldrig önskvärt och det kan leda till katastrofala resultat i olika branscher och applikationer. LÄS MER

  3. 2. Graphene-based Crack-Free Ceramic Coatings for High-Performance Passive RF Devices

    Master-uppsats, KTH/Skolan för elektroteknik och datavetenskap (EECS)

    Författare :Haomin Liu; [2021]
    Nyckelord :;

    Sammanfattning : Dielectric resonators coated with highly conductive metallic layers are widely used in radio frequency (RF) applications. The quality factor (Q-factor) of resonators is a key figure-of-merit that describes the loss and the energy efficiency of the resonators. LÄS MER

  4. 3. Method evaluation : Electrical surface resistance measurements on coated conductive textiles

    Master-uppsats, Högskolan i Borås/Akademin för textil, teknik och ekonomi

    Författare :Grete Wisung; [2018]
    Nyckelord :Electrical surface resistance; four-point probe; conductive textiles; conductive coatings; anisotropic materials.;

    Sammanfattning :  This thesis has evaluated how electrical surface resistance can be measured on conductive coated textiles using two different probes. The electrical surface resistance is a measurement for how difficult it is for current to flow through a material. LÄS MER

  5. 4. Polymer-based conductive fibers

    Kandidat-uppsats, Högskolan i Borås/Akademin för textil, teknik och ekonomi

    Författare :Fredrik Karlsson; Erik Söderlöv; [2016]
    Nyckelord :PEDOT poly 3; 4-ethylenedioxythiophene ; VPP vapor phase polymerization ; CVD chemical vapor deposition ; Lyocell;

    Sammanfattning : Conductive polymers, since from their discovery, have become a prominent area of research and found many useful applications in all fields of our daily life. Examples are light emitting diodes, heat generation, chemical sensors and electro-active membranes. Polymer coated textile substrates give flexible and lightweight materials. LÄS MER
