  1. 1. Reprocessing and Characterization of Polybenzimidazole for High-Temperature Polymer Electrolyte Membrane Fuel Cells

    University essay from Lunds universitet/Centrum för analys och syntes

    Author : Douglas Björkengren; [2023]
    Keywords : polymer electrolyte membrane fuel cells; PEMFC; HTPEMFC; polymer technology; polymer characterization; reprocessing; recycling; polybenzimidazole; PBI; Technology and Engineering;

    Abstract : A reprocessing method of poly(2,2’-(m-phenylene)-5,5’-bibenzimidazole) (PBI) membranes recovered from the production line of High-Temperature Polymer Electrolyte Membrane Fuel Cells (HT-PEMFC) at Blue World Technologies (BWT) has been developed in order to reduce material loss in the production. Redissolution of scrap PBI membranes in poly(phosphoric acid) (PPA) and phosphoric acid (PA) was successful and the subsequent washing procedure produced PBI that could be redissolved in N,N-dimethyl acetamide (DMAc) and suitable for solution casting of new membranes.

  5. 4. Surface Functionalization of Nanowires Using Silane-PEG Compounds

    University essay from Lunds universitet/Centrum för analys och syntes

    Author : Hedvig Ekfors Elvin; [2022]
    Keywords : Functionalization; Nanowires; Silanization; Surface Chemistry; Materials Chemistry; Chemistry;

    Abstract : Introduction: GaP nanowires were functionalized using silane-PEG-NH2 and compared with cellulose acetate, PAcrAm™-g-(PMOXA, amine, silane) and a non-functionalized reference sample. Functionalization would allow strong, covalent anchoring of antibodies instead of adsorption. READ MORE
