4. 23. Improved Adhesion Between Ethylene Polymers and Aluminium

   Författare :Anders Strålin; Chalmers tekniska högskola; []
   Nyckelord :NATURVETENSKAP; NATURAL SCIENCES;

   Sammanfattning : Adhesion between aluminium and polymers is important in a wide variety of applications. The aim of the present work was to improve adhesion in polyethylene- aluminium laminates by surface modification of aluminium. The treatments examined were hydration in boiling water and phosphatation by immersion in dilute phosphoric acid solutions. LÄS MER

5. 24. Template-Based fabrication of Nanostructured Materials

   Författare :Anders Johansson; Mats Boman; Kornelius Nielsch; Uppsala universitet; []
   Nyckelord :Inorganic chemistry; Nanoparticles; nanotubes; anodic aluminium oxide; electroless deposition; ALD; Nb2O5; Prussian blue; palladium; copper; ion beam lithography; TiO2; SiO2; Oorganisk kemi;

   Sammanfattning : Materials prepared on the nanoscale often exhibit many different properties compared to the same materials in their bulk-state. Interest in nanostructured materials has increased because of these properties in fields such as microelectronics, catalysis, optics and sensors. LÄS MER

7. 25. An in situ spectro-electrochemical study of aluminium/polymer interfaces : development of ATR-FTIR and its integration with EIS for corrosion studies

   Författare :Maria Öhman; Christofer Leygraf; Jan-Olov Nilsson; KTH; []
   Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; : ATR-FTIR; EIS; spectro-electrochemical; interface; aluminium; polymer; Other chemistry; Övrig kemi;

   Sammanfattning : In order to extend the applications of aluminium, organic coatings may be applied on sheet materials, for instance for corrosion protection or aesthetic surface finish purposes in the automotive and construction industries, or on foil materials in the flexible packaging industry. The most common mechanisms for deterioration and structural failure of organically coated aluminium structures are triggered by exposures to the surrounding environment. LÄS MER
