Session: General Poster:

Bio-based polymers have gained tremendous attention from researchers around the world in the past 20 years, while attention to bio-based polymer composites is approximately five times smaller, if judged by the number of scientific publications. Polymer composites with increased bio-based content show great promise to improve green chemistry approach attempts for environmental care.
Modified vegetable oils have already proven themselves as viable for photopolymerization process, but they still lack in product properties. Different fillers are used for all polymer’s bio-based or not and should be used for bio-based composite development. Nanocellulose as a renewable filler shows potential with its mechanical and thermal properties.
This report contains results of thermal properties investigations of vegetable oil-based photocurable composite resin with modified nanofibrilated cellulose (NFC): unseparated lignin; mild bleached; bleached.
Adaptation of the prepared UV-sensitive resin, using the composition and the functionalization of the variance of modified NFC components in the polymer-nanofiller interface, provides the properties required for the photocurable polymer composites. The ability to control the properties at the interface of biocomponents and the evaluation of their impact on micro and macroscopic properties provide a new aspect in the development of bio-nanocomposites. Photocuring kinetics, thermal conductivity and stability are discussed.
