  3. 2. Novel oil resistant cellulosic materials

    Författare :Christian Aulin; Lars Wågberg; Derek Gray; KTH; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; oleophobic; MFC; cellulose; oil resistant; contact angle; XPS; SEM; Cellulose and paper engineering; Cellulosa- och pappersteknik;

    Sammanfattning : The aim of this study has been to prepare and characterise oil resistant cellulosic materials, ranging from model surfaces to papers and aerogels. The cellulosic materials were made oil resistant by chemical and topographic modifications, based on surface energy, surface roughness and barrier approaches. LÄS MER

  4. 3. Interactions Between Biopolymers and Surfactants with Focus on Fluorosurfactants and Proteins

    Författare :Lubica Macáková; Per Claesson; Fredrik Höök; KTH; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; Organic chemistry; Organisk kemi;

    Sammanfattning : The aim of this thesis was to obtain a better understanding of the association between surfactants and biopolymers in bulk solutions and at solid/aqueous liquid interface. In order to do this, the interactions between surfactants and biopolymers were investigated with a variety of experimental techniques. LÄS MER
