1. Sustainable synthetic pathways towards the formation of bio-based polymeric materials
Abstract : Increasing environmental and social awareness arising from the use of oil as main source of raw materials, has awaken the interest of many scientists to explore new synthetic pathways for polymer production. These new approaches embrace the use of alternative feedstock and sustainable synthetic routes aiming for enhancing biodegradability and recyclability. READ MORE

2. High Performance Bio-based Composites : Mechanical and Environmental Durability
Abstract : The presented work is a part of the ongoing effort on the development of high performance bio-based composites with enhanced durability, under static and dynamic mechanical loading including the exposure to elevated humidity. The impact of relative humidity on the performance of cellulosic fibers (natural and regenerated), bio-based resins and their composites was studied. READ MORE

3. Hydrophobization of cellulose for bio-based materials
Abstract : 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. READ MORE

4. Stimuli-Responsive Materials Derived from Cellulose Nanofibrils : Synthesis, characterization, and performance evaluation
Abstract : 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.

5. Bio-based Composites from Soybean Oil Thermosets and Natural Fibers
Abstract : In order to reduce over-dependency on fossil fuels and to create an environment that is free of non-degradable plastics, and most importantly to reduce greenhouse gas emission, bio-based products are being developed from renewable resources through intense research to substitute conventional petrochemical-based plastics with renewable alternatives and to replace synthetic fibers with natural fibers. Many authors have done quite a lot of work on synthesizing polymers from renewable origin. READ MORE
