1. 1. Preparation, characterisation and wetting of fluorinated cellulose surfaces

   Författare :Christian Aulin; Lars Wågberg; Sigbritt Karlsson; KTH; []
   Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Cellulose and paper engineering; Cellulosa- och pappersteknik;

   Sammanfattning : This thesis deals with the wetting by oil mixtures of two different model cellulose surfaces. The surfaces studied were a regenerated cellulose (RG) surface prepared by spin-coating, and a film consisting of polyelectrolyte multilayers (PEM) of Poly(ethyleneimine) (PEI) and a carboxymethylated Microfibrillated Cellulose (MFC).

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
