Project description
Sustainable synthesis of 3D-printed recyclable thermosets
Photocured resins are a class of light-sensitive resins that solidify when exposed to ultraviolet or visible light, but they are mainly derived from petroleum, a non-renewable resource. Funded by the Marie Skłodowska-Curie Actions programme, the SUSTAINABLE project plans to develop a bio-based resin that can be used in the synthesis of 3D-printed self-healing and recyclable thermosets. The project will investigate a more flexible alternative to conventional ultraviolet light for thermoset curing, namely the use of cold atmospheric pressure plasma. This work will contribute to the transition towards sustainable chemistry.
Objective
With the increasing concerns on the environmental issues and with the depletion of fossil-based resources, sustainable chemistries for the development of resins from bio-based molecules and for the reprocessing and recycling of plastics are strongly demanded. In this context, SUSTAINABLE is aimed at developing inedited photopolymerizable bio-based resins employable for the 3D-printing of green, self-healing and recyclable thermosets. While photopolymerization 3D-printing has been widely employed for the obtainment and chemical optimization of thermosets from fossil-based resources, few scientific works have dealt with the design of bio-based photopolymerizable resins for 3D-printing. To complete the curing of the thermosets, the project will investigate an innovative cold atmospheric pressure plasma (CAP) assisted approach, as a more flexible alternative to the conventional UV exposure.
SUSTAINABLE, proposing possible strategies to reduce the environmental issues linked to the single-use plastic devices disposal, contributes to the achievement of Goal 12: “Ensure sustainable consumption and production pattern” of United Nations’ Sustainable Development Goals.
The programme will be developed by a researcher with a PhD in Engineering and skills on design, realization and optimization of CAP sources for materials processing; the fellowship will be performed at KTH in Stockholm, under the supervision of Prof. M. Hakkarainen, who has acknowledged expertise in the synthesis, processing and end-of-life management of bio-based, degradable and/or recyclable plastics.
SUSTAINABLE requires expertise from organic chemistry, materials manufacturing and processing, materials characterization and will thereby diversify the competences of both the researcher and the Host Group. This action prepares the fellow for the achievement of a more permanent position by endowing her with crucial opportunities to gain new scientific competences and improving her transversal skills.
