1. 6. Polymerization of isatin towards polymers for anion exchange membranes and gas separation applications

   University essay from Lunds universitet/Kemiska institutionen

   Author : Simone Facchini; [2022]
   Keywords : organic chemistry; membranes; isatin; polymers; Chemistry;

   Abstract : In a world where the problem of energy resources, pollution and all aspects related to these issues becomes more and more dominant, a greater commitment is needed in the search for solutions. The goal of this project is to make a contribution to the research and development of new materials to reduce the environmental impact in some fields. READ MORE

3. 7. Synthesis and Investigation of Nitrile-Containing Polymers Inspired by Lignin

   University essay from Lunds universitet/Centrum för analys och syntes

   Author : Tobias Lindborg; [2022]
   Keywords : Lignin; Polymer; Renewable; Bioresource; Glass transition temperature; Nitrile; Polymer technology; Chemistry; Technology and Engineering;

   Abstract : The lignin-inspired derivatives coniferyl aldehyde and sinapyl aldehyde were used to prepare nitrile-containing methacrylate monomers with the aim to synthesize bio-based polymers exhibiting high glass transition temperatures (Tgs). The aldehydes were initially transformed to the corresponding nitriles and then underwent methacrylation before being polymerised by free-radical polymerisation. READ MORE

4. 8. Block copolymer-based hybrid nanomaterials for nanoimprint applications

   University essay from Lunds universitet/Fasta tillståndets fysik; Lunds universitet/Lunds Tekniska Högskola

   Author : Philip Sellin; [2022]
   Keywords : Block copolymer; Sequential infiltration synthesis; Nanoimprint lithography; Reactive ion etching; Self-assembly; Thermal annealing; Solvent vapour annealing; Nanoprocessing; Nanofabrication; Antibacterial; Technology and Engineering;

   Abstract : In this Master’s thesis project, a block copolymer (BCP) film was used in combination with sequential infiltration synthesis and etching to manufacture a nanoimprint lithography stamp consisting of silicon. The BCP film was designed to contain perpendicularly aligned hexagonally placed cylinders, a pattern that will later be investigated for antibacterial properties after being transferred via nanoimprint lithography to a polymer film.

5. 9. Development Of Bio-Based Thermosetting Resins

   University essay from Högskolan i Borås/Akademin för textil, teknik och ekonomi

   Author : Snehaben Gaurangkumar Mistry; [2021]
   Keywords : Bio-based polymer; Resin; lactide; lactone; isosorbide; butanediol; polymerisation; characterisation; FTIR; NMR; TGA; DMA;

   Abstract : Thermoset polymers are widely used polymers in the world, but Increase in global plastic pollution and lack of fossil fuel stimulates intense research towards environmentally sustainable materials. Bio-based unsaturated polyesters (UPs) would be an excellent solution to replace oil-based synthetic polyesters. READ MORE

6. 10. Synthesis of a polar conjugated polythiophene for 3D-printing of complex coacervates

   University essay from Linköpings universitet/Laboratoriet för organisk elektronik; Linköpings universitet/Tekniska fakulteten

   Author : Johanna Heimonen; [2021]
   Keywords : conjugated polymers; polythiophene; crosslinking; Suzuki polymerization; OMIEC; complex coacervate; water soluble polymer; Kemi; Kemi;

   Abstract : The aim of this thesis was to synthesize a functionalized polar conjugated polythiophene that could be (3D-) printed into form-stable structures for bio-interfacing. The material design rationale aimed for a water-processable polymer that had the capability of electronic and ionic conduction, by using a thiophene backbone and oligoethylene side chains. READ MORE
