6. Design of Cellulose-based Materials by Supramolecular Assemblies
Sammanfattning : Due to climate change and plastic pollution, there is an increasing demand for bio-based materials with similar properties to those of common plastics yet biodegradable. In this respect, cellulose is a strong candidate that is already being refined on a large industrial scale, but the properties differ significantly from those of common plastics in terms of shapeability and water-resilience.

7. Development and Tailoring of Low‐Density Cellulose‐Based Structures for Water Treatment
Sammanfattning : The challenges posed by our limited clean water sources and the well-known global water pollution demand more efficient water purification technologies. Additionally, the increasing environmental awareness has inspired a shift towards eco-friendly and renewable materials and technologies. LÄS MER
8. Stimuli-Responsive Materials Derived from Cellulose Nanofibrils : Synthesis, characterization, and performance evaluation
Sammanfattning : This thesis presents a comprehensive study on stimuli-responsive materials derived from cellulose nanofibrils (CNFs), focusing on their synthesis, characterization, and performance evaluation in various applications. Renowned for their biodegradability, renewability, and robust mechanical properties, CNFs are explored in three primary contexts: moisture-responsive actuators, voltage-responsive actuators, and CO2-responsive sensors.

9. Chemical Modification of Electrospun Cellulose Nanofibers
Sammanfattning : The forest industry is a large part of the Swedish economy and the export of pulp, paper and wood products constitutes 11% of the total Swedish export of goods. The main product of a pulp mill is purified cellulose, which has many great properties like biodegradability and non-toxicity. LÄS MER
10. Colloidal interactions and arrested dynamics of cellulose nanofibrils
Sammanfattning : Over the past decades, concerns for the environment have increased and efforts to achieve a sustainable society have intensified. One particular challenge is to replace fossil-based plastics with biodegradable materials produced from renewable resources. LÄS MER
