  1. 1. Towards an understanding of surface hydrophobization of paper - Exploring the effect of polymer nanoparticles, starch, ionic strength and process parameters

    Författare :Frida Iselau; Chalmers tekniska högskola; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; NATURVETENSKAP; NATURAL SCIENCES; starch; ionic strength; paper hydrophobization; nanoparticles; penetration.; kinetics; charge ratio; temperature; aggregation; Surface sizing;

    Sammanfattning : Paper materials are cost effective and lightweight, they can easily be recycled and their use as an alternative to plastics is advantageous from an environmental and sustainability perspective. However, competing with plastics for packaging applications is a challenge for cellulosic products. LÄS MER

  4. 3. Hydrophobization of cellulose for bio-based materials

    Författare :Tianxiao Huang; Monica Ek; Merima Hasani; KTH; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Betulin; Cellulose; Hydrophobicity; Mechanical properties; Polymer-matrix composites; Sustainability; Textile; Betulin; Cellulosa; Hydrofobicitet; Hållbarhet; Mekaniska egenskaper; Polymer-matriskompositer; Textil; Fiber- och polymervetenskap; Fibre and Polymer Science;

    Sammanfattning : Cellulosa, vilken är huvudkomponenten i växter förekommer rikligt i naturen, både på land och i havet. Cellulosabaserade material har i tusentals år använts av människan för dagliga förnödenheter som bränsle och konstruktionsmaterial. Cellulosa isolerades först av den franske forskaren Anselme Payen 1838. LÄS MER
