  1. 6. Photocuring of multifunctional monomers initiated by camphorquinone / amine systems for application in dental restorative resins

    Författare :Nie Jun; Karolinska Institutet; Karolinska Institutet; []
    Nyckelord :Photocuring; Dental restorative resins; Photoinitiator system: Cainphorquinone amines; Monomers: Meth acrylates; Photoinitiated polymerization kinetics;

    Sammanfattning : This thesis deals with the photopolymerization of mono-, di- and trifunctional monomers initiated by carnphorquinone (CQ) alone and/or with different amines (AMH) as coinitiators in air as well in nitrogen. The kinetics of photopolymerization was measured by photoisothermal calorimetry (photo-DSC), which allowed the measurement of the rate of polymerization (Rp), maximum rate of polymerization (Rpmax), time of inhibition (tinh), time at which Rpmax was obtained (tmax), double bond conversion (p) and maximum double bond conversion (pmax).

  3. 7. Neutron Reflectometry Studies of the Hydrated Structure of Polymer Thin Films

    Författare :Bela Nagy; Thomas Ederth; Tommy Nylander; Fabrice Cousin; Linköpings universitet; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES;

    Sammanfattning : Polymer coatings are inexpensive surface modifications providing a wide variety of functions. There is an ever-present motivation to improve the films’ performance and to decrease the cost and the environmental footprint of their production. LÄS MER

  4. 8. Photopatternable Electrolytes for Conducting Polymer Actuators

    Författare :Yong Zhong; Edwin Jager; Anthony Turner; Jose Gabriel Martinez; Aleksandar Matic; Linköpings universitet; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY;

    Sammanfattning : Electroactive polymers (EAPs) are materials that can change their dimensions or shape in response to electric stimulation. They have attracted considerable interests for their applications as soft, lightweight and silently operating polymer actuators. One significant group of EAPs is conducting polymers. LÄS MER

  5. 9. Biosensor surface chemistry for oriented protein immobilization and biochip patterning

    Författare :Emma Ericsson; Karin Enander; Sofia Svedhem; Linköpings universitet; []
    Nyckelord :Biochip; biosensor; hydrogel; ligand; orientation; patterning; photochemistry; protein immobilization; surface chemistry; self-assembled monolayer; SAM;

    Sammanfattning : This licentiate thesis is focused on two methods for protein immobilization to biosensor surfaces for future applications in protein microarray formats. The common denominator is a surface chemistry based on a gold substrate with a self-assembled monolayer (SAM) of functionalized alkanethiolates. LÄS MER

  7. 10. Grafted Molecular Layers for Control of Surface Properties

    Författare :Gunnar Dunér; Andra Dédinaité; Stefan Zauscher; KTH; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES;

    Sammanfattning : The goal of this thesis work was to develop responsive surface grafted brushlayers for control of surface properties and to gain insights in the molecular mechanisms that control these properties. Three types of grafted layers were investigated, as outlined below. LÄS MER
