  1. 1. Bio-oil based polymeric composites for additive manufacturing

    University essay from KTH/Skolan för kemi, bioteknologi och hälsa (CBH)

    Author : Suvi Muukka; [2020]
    Keywords : polymer composite; polyamide; glass fiber; microcrystalline cellulose; composite; compatibilization; additive manufacturing; polymeerikomposiitti; polyamidi; lasikuitu; mikrokiteinen selluloosa; kompatibilisaatio; materiaalia lisäävät menetelmät; polymerkomposit; polyamid; glasfiber; mikrokristallin cellulosa; kompatibilisering; additiv tillverkning;

    Abstract : Plast- och kompositindustrin har växt i årtionden och den ständigt växande världen och ny teknik kräver ännu större mängder polymerkompositer för en mängd olika tillämpningar. Numera är de negativa miljöaspekterna av polymerproduktion och plastavfall kända, men trots detta är råoljafortfarande det primära råmaterialet för de flesta polymerer. READ MORE

  3. 2. Hydrothermally carbonized wood as a component in biobased material for 3D-printing

    University essay from KTH/Skolan för kemi, bioteknologi och hälsa (CBH)

    Author : Matilda Hendeberg; [2020]
    Keywords : Hydrothermal carbonization; 3D printing; biobased materials; biodegradable;

    Abstract : Consumers put higher demands on low environmental impact from the products they use, and the materials they consist of. As a result, more research is being made on finding environmentally friendly production techniques and materials. Hydrothermal carbonization (HTC) is a relatively environmentally friendly method that has been used in this study. READ MORE

  4. 3. Development of corrosion resistant coatings using natural biopolymer and pollen

    University essay from KTH/Materialvetenskap

    Author : Alessandro Armani; [2020]
    Keywords : ;

    Abstract : Corrosion is a mechanism that highly reduces the lifetime of metals in different environments, especially in water or moisture environment. The worldwide maintenance cost due to corrosion is estimated in billions of dollars per year, and actual solutions in terms of coating usually contains toxic or environmentally harmful species.

  5. 4. Production of regenerated nanocomposite fibers based on cellulose and their use in all-cellulose composites

    University essay from Luleå tekniska universitet/Institutionen för teknikvetenskap och matematik

    Author : Andrés García Vogel; [2017]
    Keywords : All-cellulose composites; regenerated cellulose nanocomposite fibers; halloysite nanotubes; cellulose nanocrystals; LiCl DMAc; bio based;

    Abstract : Biobased all-cellulose composites (ACCs), in which the matrix and the reinforcement are made out of the same material, have gained a noticeable increased attention in recent years. Their successful application would solve the commonly faced challenges with natural fiber composites regarding their chemical antipathy between the hydrophilic fiber and the usually hydrophobic polymer matrix, while still keeping the advantages of being environmental friendly.

  6. 5. Eco Friendly Composites Prepared from Lactic Acid Based Resin and Natural Fiber

    University essay from Högskolan i Borås/Institutionen Ingenjörshögskolan

    Author : Nima Esmaeili; Shahrzad Javanshir; [2014]
    Keywords : Biobased thermoset; thermoset poly lactic acid; biobased composite; natural fiber; viscose;

    Abstract : Lactic acid based thermoset were synthesised by reacting lactic acid with glycerol andfunctionalizing lactic acid branches by methacrylic anhydride. Resins with different chainlength were prepared and their thermo mechanical properties were examined through DMAanalysis and their molecular structures were analyzed by NMR method and their viscositywere investigated through rheometry analysis and three monomers were selected as the bestchain length.
