    Sammanfattning : To produce a greener adhesive is always an issue of concern to the commercial market and global environment. The environmental request for producing greener and bio-based adhesives leads to an increased awareness of replacing fossil-based components in adhesives with bio-based alternatives. LÄS MER

  3. 2. Sustainable corrosion protection for metallic materials by Mussel adhesive protein modified lignin film

    Master-uppsats, KTH/Materialvetenskap

    Författare :Di Wang; [2020]
    Nyckelord :;

    Sammanfattning : Lignin has the potential to be used as green material to inhibit the corrosion of metallic substrates. Mussel adhesive protein is used to modify lignin due to its great adhesive and film forming abilities. LÄS MER

  4. 3. Chemical methods to increase the reactivity  of lignin : In the context of green chemistry  and education for sustainable development

    Uppsats för yrkesexamina på avancerad nivå, KTH/Skolan för teknikvetenskaplig kommunikation och lärande (ECE)

    Författare :Erica Birgersson; [2015]
    Nyckelord :Biomaterial; lignin reactivity; thiol mediated demethylation; iodine mediated demethylation; green chemistry; SNl-fall.; Biomaterial; lignin reaktivitet; tiol medierad demetylering; jod medierad demetylering; gron kemi; SNI-fall;

    Sammanfattning : The research  concerning lignin in high value applications has increased  during the last years due to its renewability and availability in the black liquor from pulp mills. Today  the major part of kraft lignin found  in the black liquor is used as fuel to gain energy  in the recovery boiler. LÄS MER
