| Abstract [eng] |
The depletion of fossil fuels and the increase in their price accelerate the society to use greener materials for their necessities. Research on biobased plastics has increased dramatically in the past 30 years while exceedingly large implications for oil-based plastics begin to unfold [1]. One way to address this issue is to use polymers derived from natural sources, such as plants. In this work, two biobased monomers: tetrahydrofurfuryl acrylate derived from hemicellulose and tridecyl methacrylate derived from natural oils, were chosen for photocross-linked polymer synthesis. A dual-curing process allowing to combine two polymerization mechanisms and thus achieve greater properties compared to separate parts [2] was used in this work. Stimuli-responsive materials, also known as shape-memory materials, have attracted researchers and industry due to their unique ability to change and maintain shape in response to external stimuli. Shape-memory polymers have a great potential to be applied in biomedicine, electronics, optics, robotics, etc. [for example, 3]. However, only a few shape-memory polymers have been synthesized by using an environmentally friendly UV-induced dual-curing method. The aim of this work was to investigate the influence of the amount of the biobased monomer tetrahydrofurfuryl acrylate on the photocuring kinetics, mechanical and thermal characteristics, and shape-memory properties of the resulting polymers. Ethyl(2,4,6-trimethylbenzoyl)phenylphosphinate was used as a photoinitiator. The chemical structure of the used compounds is presented in Figure 1. [...]. |
