  1. 1. Non-ionic block copolymers and proteins at the air-water interface

    Författare :Brita Rippner Blomqvist; Per M. Claesson; Cosima Stubenrauch; KTH; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; Physical chemistry; Fysikalisk kemi; Physical chemistry; Fysikalisk kemi;

    Sammanfattning : The behavior of block copolymer and protein films at interfaces is of central importance to their function in many application areas. Poly(ethylene oxide)-poly(propylene oxide)-poly(ethylene oxide) (PEO-PPO-PEO) block copolymers function e.g. LÄS MER

  3. 2. Polyelectrolyte complexes of bottle brush copolymers : Solution and adsorption properties

    Författare :Shovsky Alexander; Per M. Claesson; Tommy Nylander; KTH; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; Surface and colloid chemistry; Yt- och kolloidkemi;

    Sammanfattning : The aim of this thesis work was to systematically investigate the physico-chemical properties of polyelectrolyte complexes (PECs) formed by bottle brush and linear polyelectrolytes in solution and at solid / liquid interfaces. Electrostatic self-assembly of oppositely charged macromolecules in aqueous solution is a versatile strategy to construction of functional nanostructures with easily controlled properties. LÄS MER

  4. 3. Polymers in Aqueous Lubrication

    Författare :Junxue An; Per M. Claesson; Martin Malsten; KTH; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; Lubrication; boundary lubrication; friction; surface forces; adsorption; adsorption hysteresis; non-equilibrium state; diblock copolymer; polyelectrolyte; thermoresponsive; mucin; QCM-D; ellipsometry; AFM; Kemi; Chemistry;

    Sammanfattning : The main objective of this thesis work was to gain understanding of the layer properties and polymer structures that were able to aid lubrication in aqueous media. To this end, three types of polyelectrolytes: a diblock copolymer, a train-of-brushes and two brush-with-anchor mucins have been utilized. LÄS MER

  5. 4. Self assembly of surfactants and polyelectrolytes in solution and at interfaces

    Författare :Luis Alejandro Bastardo Zambrano; Per Claesson; Jan Skov Pedersen; KTH; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; Surfactant; polyelectrolyte; small–angle neutron scattering; static light scattering; dynamic light scattering; polyelectrolyte–surfactant association; protein; Surface and colloid chemistry; Yt- och kolloidkemi;

    Sammanfattning : This thesis focuses on the study of the interactions between polyelectrolytes and surfactants in aqueous solutions and at interfaces, as well as on the structural changes these molecules undergo due to that interaction. Small–angle neutron scattering, dynamic, and static light scattering were the main techniques used to investigate the interactions in bulk. LÄS MER
