  1. 26. On processing of thermoplastic starch

    Författare :Mats Thunwall; Chalmers tekniska högskola; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; amylose; starch; extrusion; thermoplastic starch;

    Sammanfattning : Starch is a biodegradable material produced in many different crop plants. Since it is biodegradable, inexpensive, generally has good barrier properties and comes from a renewable source it would be an ideal material to use in e.g. packaging applications. LÄS MER

  3. 27. NMR Diffusometry and Dynamic NMR Microscopy Studies of Colloidal Systems

    Författare :Helena Wassenius; Chalmers tekniska högskola; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; diffusion behaviour; dynamic NMR microscopy; NMR diffusometry; core-shell latex particles; NMR velocimetry; rheology; colloidal systems;

    Sammanfattning : In this thesis, the NMR diffusometry and dynamic NMR microscopy methods were shown to be useful techniques with a great potential for the study of colloidal systems. In Paper I-II, NMR diffusometry was used to study the behaviour of surfactant and polymer molecules that are normally important components in colloidal dispersions and emulsions. LÄS MER

  4. 28. Towards a mechanism for surface hydrophobization of paper - Effect of combinations of polyelectrolytes and polymer particles

    Författare :Frida Iselau; Chalmers tekniska högskola; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; nanoparticles; kinetics.; paper hydrophobization; starch; Surface sizing; interactions; aggregation;

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

  5. 29. Biocomposites Based on Core-Shell Cellulose Nanofibers : Preparation, Structure, and Properties

    Författare :Kasinee Prakobna; Lars Berglund; David Plackett; KTH; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; biocomposites; cellulose nanofibers; polysaccharides; holocellulose; nanostructure; dispersion; mechanical properties; hygromechanical properties; moisture stability; film; porous material; Fiber- och polymervetenskap; Fibre and Polymer Science;

    Sammanfattning : Cellulose nanofibers (CNFs) are of interest as load-bearing components for polymer matrix nanocomposites. A wide range of nanostructured materials including nanopaper/films, foams, aerogels, and hydrogels can be prepared from CNFs. The material performance can be fine-tuned when CNFs are combined with different polymer matrices. LÄS MER

  7. 30. Potato Starch Dispersions: Structure and Rheology

    Författare :Karin Svegmark; Chalmers tekniska högskola; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES;

    Sammanfattning : The influence of heating, shearing and addition of amylose on the structure and rheology of potato starch dispersions has been evaluated. The methods used were dynamic viscoelastic measurements, light microscopy and transmission electron microscopy (TEM). LÄS MER
