  1. 6. 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. 7. Barrier properties of model coatings using recycled iron oxide pigment

    Uppsats för yrkesexamina på grundnivå, KTH/Skolan för kemi, bioteknologi och hälsa (CBH)

    Författare :Nathalie Hagenfjärd; [2021]
    Nyckelord :Organic coatings; Iron oxide pigment; EIS; Barrier properties;

    Sammanfattning : The aim of this study was to compare the barrier properties of organic coatings with the same polymer matrix but different types of iron oxide particles, commercial and recycled. The work was carried out for the company SSAB with the aim of investigating whether the pigment Merox ferric oxide, which is produced in-house at the company during the pickling process, can be used and replace commercial iron oxide pigment.

  4. 8. Investigation and Application of Safety Parameters for Lithium-ion Battery Systems

    Master-uppsats, KTH/Skolan för kemi, bioteknologi och hälsa (CBH)

    Författare :Axel Relefors; [2020]
    Nyckelord :Lithium-ion battery; thermal runaway; accelerating rate calorimetry; electrochemical impedance spectroscopy; thermal management; Litiumjonbatteri; termisk rusning; kalorimeter; elektrokemisk impedansspektroskopi; värmereglering;

    Sammanfattning : The Swedish Armed Forces are investigating high-risk applications where lithium-ion batteries (LIB) can replace traditional lead-acid batteries. Understanding the potential safety risks and evaluating a battery's instability is crucial for military applications. LÄS MER

  5. 9. Development and 3D Printing of Intrinsically Stretchable Materials for Microsupercapacitors

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

    Författare :Alexander Engman; [2020]
    Nyckelord :Stretchable electronics; Printed electronics; 3D printing; Direct Ink Writing; Additive manufacturing; Printed supercapacitor; Sträckbar elektronik; Tryckt elektronik; Friformsframställning; Direct InkWriting; Additiv tillverkning; Tryckt superkondensator;

    Sammanfattning : The purpose of this thesis is to develop a simple Direct Ink Writing (DIW) method for fabricating intrinsically stretchable microsupercapacitors as ef- fective on-chip energy storage devices for the emerging stretchable electron- ics. Using the printing method for fabricating intrinsically stretchable elec- tronic components remains a novel approach. LÄS MER

  7. 10. Sustainable corrosion protection for metallic materials by Mussel adhesive protein modified lignin film

    Master-uppsats, KTH/Materialvetenskap

    Författare :Di Wang; [2020]
    Nyckelord :;

    Sammanfattning : Lignin has the potential to be used as green material to inhibit the corrosion of metallic substrates. Mussel adhesive protein is used to modify lignin due to its great adhesive and film forming abilities. LÄS MER
