1. 1. 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

3. 2. Functional composite coatings containing conducting polymers

   Författare :Shadi Jafarzadeh; Per Martin Claesson; Arjan Mol; KTH; []
   Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Conducting polymer; Polyaniline; Conductive network; Nanocomposite; Active corrosion protection; Interfacial energy; UV curing; Kemi; Chemistry;

   Sammanfattning : Organic coatings are widely used to lower the corrosion rate of metallic structures. However, penetration of water, oxygen and corrosive ions through pores present in the coating results in corrosion initiation and propagation once these species reach the metal substrate. LÄS MER
