Completed R&D
A project funded by the Swedish wood chemistry company Södra in cooperation with the Swedish research institution RISE "Cellulose based energy harvesting“
01.01.2023–31.12.2023
In the course of the project, the possibilities of using various materials produced by the chemical valorization of cellulose for the collection of electrical energy using the triboelectric method are investigated. In the Laboratory of Biopolymer Technology of Tallinn University of Technology, cellulose derivatives are prepared and nanofibrous non-woven materials are produced from them by electrospinning. The main physical properties of non-woven materials are determined. Project partner RISE constructs triboelectric devices from the non-woven materials and evaluates their ability to produce electricity.
Partnership with the Institute of Technology of the University of Tartu: " Promoting the novel bio-based materials for the sustainable polymer industry“
01.05.2023–31.10.2023
The project builds on the results and novel technology developed in BioStyrene project (ER30) and focuses on extending these results.
State funding to support R&D on resource valorisation (RESTA)" Chemical valorisation of cellulose in environment of ionic liquids“
01.09.2020–31.08.2023
Sustainable thermoplastic polymers are developed and investigated to partly or fully replace non-renewable-resources-based materials for melt processing technologies. Cellulose appears to be a nearly unlimited renewable resource for polymeric materials. Discovery of dissolution processes of cellulose in ionic liquids opens several new routes for functionalization. Thermoplastic cellulose derivatives can be prepared without use of plasticizers, by attaching long-chain ester branches to the macromolecule of cellulose. Effect of functionalization agents and conditions in medium of ionic liquids on rheology, crystallization behaviour, morphology and mechanical properties of the novel thermoplastic materials is investigated. A laboratory line for pilot production of the novel thermoplastic materials will be started. Producing and processing parameters of the novel materials will be clarified for further commodity applications.
Partnership with the National Institute of Chemical Physics and Biophysics: " Novel nanoparticle-based filter materials and face masks for SARS-CoV-2 inactivation"
01.10.2020–31.12.2021
The main goal of the current project is to develop new virucidal filtering materials and produce face masks from thereof. We will 1) test a set of antiseptical nanoparticels and choose the ones that are the most effective against SARS-CoV-2; 2) produce nanoparticles-containing filtering materials and the face masks. There are three science partners (NICPB, UT, TalTech) and one industrial partner (Esfil Tehno) in the project. NICPB will characterize nanoparticles, TalTech will develop filtering materials, Esfil Tehno will produce the face masks and UT will conduct virological tests. The main outcome of the project are novel efficient virucidal face masks produced by the local industry.
European Space Agency (ESA) funded project in cooperation with Skeleton Technologies OÜ: " Fully electrospun durable electrode and electrochemical double-layer capacitor for high frequency applications“
01.01.2017–31.12.2018
The main objective of the project is to develop fully electrospun, nanofibrous electrochemical double-layer capacitor, which is suitable for high frequency applications without significant loss of capacitance under specific environmental conditions of space missions. The additional objective is to have the supercapacitor in form of flexible and stackable thin sheets. This is useful for the most efficient usage of confined space of (micro)satellite or spacecraft. Still, this is not retracting usage of the new type of electrochemical double-layer capacitors in traditional housings.
