  1. 16. Radiation crosslinking of cellulose fibers to obtain rigid lightweight paperboard

    Författare :Mikaela Börjesson; Chalmers tekniska högskola; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; NATURVETENSKAP; NATURAL SCIENCES; Paper; Modification; Ester; Crosslinking; Cellulose; UV radiation; Acrylates; Packaging;

    Sammanfattning : Cellulosic materials are used in a wide range of areas of application, and one of these is paperboard for packaging solutions. Paper or paperboard as a packaging material has benefits like low density, low costs, high stiffness, good printability, and paper is environmentally friendly. LÄS MER

    Sammanfattning : Increased use of environmentally acceptable chemicals and reduced energy consumption are two foreseeable demands within the ceramics industry. This will require the replacement of organic solvents and lowering of sintering temperatures. LÄS MER

  4. 18. Combustion dynamics and melt dripping of ethylene-acrylate copolyer composites

    Författare :Roland H. Krämer; Ulf W. Gedde; Mats Jonsson; KTH; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; methacrylic acid; ethylene; calcium carbonate; ionomer; nanoparticles; intumescence; halogen-free; flame retardant; melt dripping; Polymer chemistry; Polymerkemi;

    Sammanfattning : The degradation and combustion of blends of ethylene-acryalte copolymer with calcium carbonate and silicone were studied by a combination of flammability tests, in-situ measurements and analytical experiments. Compounds of poly(ethylene-co-methacrylic acid) blended with precipitated calcium carbonate nanoparticles were prepared. LÄS MER

    Sammanfattning : This thesis aims at characterizing tridimensional (3D) printed polymers onto PET textile materials via fused deposition modeling (FDM) that uses both non-conductive and conductive polymers, optimizing their mechanical and electrical properties through statistical modeling and enhancing them with pre and post-treatments and the development of polymer blends. This research work supports the development of technical textiles through 3D printing that may have functionalities. LÄS MER
