1. 1. 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

3. 2. The effects of cellulosic fiber charges on polyelectrolyte adsorption and fiber-fiber interactions
