    Kandidat-uppsats, KTH/Kemiteknik

    Författare :Sara El Ghamri; Ed Kammeby; Herman Göransson; Arvid Stjerngren; [2023]
    Nyckelord :Bionedbrytbara biosensorer; Biodegradable biosenors; Organic mixed ionic–electronic conductors; Carboxyl esterase; organic electrochemical transistors; poly trimethylene carbonate ;

    Sammanfattning : This report aims to study the degradation of poly(trimethylene carbonate) (PTMC) caused by the enzyme carboxylesterase in vitro. As well as to characterise polymer blends of f-BTI2g-TVTCN and poly(3-hydroxybutyric acid) as core components for organic electrochemical transistors (OETCs). LÄS MER

  3. 2. Investigation of stability in high salt polymer electrolytes for sodium batteries

    Master-uppsats, Uppsala universitet/Strukturkemi

    Författare :Fengnan Yuan; [2022]
    Nyckelord :;

    Sammanfattning : Poly(trimethylene carbonate)–sodium bis(fluorosulfonyl)imide system shows a promising performance as polymer-in-salt electrolytes. The polymer electrolytes with salts concentration from 62% to 71% were tested through DSC, FTIR, EIS and constant current cycling. The solubility of the salts varies in different salts in PTMC.

  4. 3. Probing ion movement in conjugated polymers

    Uppsats för yrkesexamina på avancerad nivå, Uppsala universitet/Strukturkemi

    Författare :Markus Hall; [2019]
    Nyckelord :Light-emitting electrochemical cell; conjugated polymer; electrochemical doping; MEH-PPV; lithium; trifluoromethanesulfonate; trimethylolpropane ethoxylate;

    Sammanfattning : Electronic conduction in conjugated polymers can be increased through electrochemical doping. This is utilised in light-emitting electrochemical cells and allows for a less demanding manufacturing process compared to the related organic light-emitting diode. LÄS MER

  5. 4. Synthesis of polycarbonate polymer electrolytes for lithium ion batteries and study of additives to raise the ionic conductivity

    Uppsats för yrkesexamina på avancerad nivå, Uppsala universitet/Strukturkemi

    Författare :Jonas Andersson; [2015]
    Nyckelord :battery materials; polymer electrolyte; PTMC; poly trimethylenecarbonate ; LiTFSI; nanofillers; batterimaterial; polymerelektrolyt; PTMC; polytrimetylkarbonat; LiTFSI; nanofillers;

    Sammanfattning : Polymer electrolyte films based on poly(trimethylene carbonate) (PTMC) mixed with LiTFSI salt in different compositions were synthesized and investigated as electrolytes for lithium ion batteries, where the ionic conductivity is the most interesting material property. Electrochemical impedance spectroscopy (EIS) and DSC were used to measure the ionic conductivity and thermal properties, respectively. LÄS MER

  7. 5. PTMC: A polycarbonate candidate for polymer electrolytes in sodium batteries? : A characterisation of the PTMC–NaFSI system

    Uppsats för yrkesexamina på avancerad nivå, Uppsala universitet/Strukturkemi

    Författare :Ronnie Mogensen; [2015]
    Nyckelord :sodium; polymer battery; PTMC;

    Sammanfattning : The poly(trimethylene carbonate)–sodium bis(fluorosulfonyl)imide system has been investigated as polymer electrolytes for sodium batteries. The properties of poly(trimethylene carbonate) with salt concentrations ranging from 8.7wt% to 67wt% have been measured by DSC, FTIR, and EIS. LÄS MER
