  2. 1. Fabrication of polymeric microfluidic devices via photocurable liquid monomers

    University dissertation from Stockholm : KTH

    Author : Klas Tommy Haraldsson; Mats K. G. Johansson; Ken Carter; [2005]
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; Photopolymerization; radical photopolymerization; polymerization kinetics; photoinitiation; vinyl ether; maleate; vinyloxy; NATURAL SCIENCES Chemistry Organic chemistry Polymer chemistry; NATURVETENSKAP Kemi Organisk kemi Polymerkemi;

    Abstract : Microfluidic devices have long been considered an ideal tool for rapid and inexpensive chemical analysis and reactions in areas ranging from point-of-care health to national security applications. However, fabricating microfluidic devices is time consuming, difficult and above all expensive. READ MORE

  4. 2. Exploring bio-based monomers for UV-curable polymer networks

    University dissertation from Stockholm : KTH Royal Institute of Technology

    Author : Sara Brännström; Eva Malmström; Yves Leterrier; [2019]
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; Bio-based; polymers; vinyl ether; polyester; photopolymerization; lipase; Fiber- och polymervetenskap; Fibre and Polymer Science;

    Abstract : Increased environmental awareness and concern has led to a high demand for sustainable, bio-based materials. Consequently, there is a need for research and development of new bio-based polymeric materials that can be synthesized via routes eliminating excessively toxic reactants and by-products. READ MORE

  5. 3. Signal Enhancement by Dynamic Polymers in Quartz Crystal Microbalance Applications

    University dissertation from Stockholm : KTH

    Abstract :  This licentiate thesis presents studies of signal enhancement by dynamic polymers in quartz crystal microbalance (QCM) applications. The aim of the study has been to determine the potential for the use of polymers on QCM sensors for signal enhancement in molecular interaction studies. READ MORE

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

    University dissertation from Stockholm : Karolinska Institutet, -

    Author : Nie Jun; Karolinska Institutet.; Karolinska Institutet.; [1998]
    Keywords : MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; Photocuring; Dental restorative resins; Photoinitiator system: Cainphorquinone amines; Monomers: Meth acrylates; Photoinitiated polymerization kinetics;

    Abstract : 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).

  7. 5. Photopatternable Electrolytes for Conducting Polymer Actuators

    University dissertation from Linköping : Linköping University Electronic Press

    Author : Yong Zhong; Edwin Jager; Anthony Turner; Jose Gabriel Martinez; Aleksandar Matic; [2019]
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY;

    Abstract : 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. READ MORE
