  1. 21. Isocyanate-free polyurethane from cyclic carbonates : Synthesis, application and evaluation

    University essay from Lunds universitet/Centrum för analys och syntes

    Author : Christoffer Wallerek; [2016]
    Keywords : Isocyanate; polyurethane; cyclic; carbonate; NIPU; polymer; PU; polymer technology; Technology and Engineering; Chemistry;

    Abstract : Polyurethane is a widely used polymer with a lot of different applications due to its versatility and often resilient properties. The polymeris often prepared as a two component system consisting of polyols and isocyanates and can be cured at relatively low temperatures. READ MORE

  3. 22. Graphene-based Coatings for Heat Exchangers

    University essay from Lunds universitet/Centrum för analys och syntes

    Author : Marie Långberg; [2015]
    Keywords : Polyaniline; graphene; materials chemistry; materialkemi; Chemistry;

    Abstract : This master thesis is a part of a larger interwork between SP, KTH and Alfa Laval funded by the SIO graphene programme, which end goal is to formulate an anti-corrosion coating based on graphene or graphene related materials (GRMs). The investigation is partly based on an article “Novel anticorrosion coatings prepared from polyaniline/graphene composites” from 2012 by Chang et al in combination of knowledge acquired during a previous EU project, www.

  4. 23. Synthesis and electrochemical characterisation of processable polypyrrole boronic acid derivatives for carbohydrate binding

    University essay from Linköpings universitet/Biosensorer och bioelektronik; Linköpings universitet/Tekniska fakulteten

    Author : Kalle Bunnfors; [2015]
    Keywords : Conducting polymers; polypyrrole; boronic acid; carbohydrates; reagent-free detection.;

    Abstract : Conducting polymers have been widely explored for many different purposes including sensing. In thisthesis the conducive properties of pyrrole and the carbohydrate binding properties of boronic acid iscombined to make a reagent-free detector for carbohydrates. READ MORE

  5. 24. Synthesis of polycarbonate polymer electrolytes for lithium ion batteries and study of additives to raise the ionic conductivity

    University essay from Uppsala universitet/Strukturkemi

    Author : Jonas Andersson; [2015]
    Keywords : battery materials; polymer electrolyte; PTMC; poly trimethylenecarbonate ; LiTFSI; nanofillers; batterimaterial; polymerelektrolyt; PTMC; polytrimetylkarbonat; LiTFSI; nanofillers;

    Abstract : Polymer electrolyte films based on poly(trimethylene carbonate) (PTMC) mixed with LiTFSI salt in different compositions were synthesized and investigated as electrolytes for lithium ion batteries, where the ionic conductivity is the most interesting material property. Electrochemical impedance spectroscopy (EIS) and DSC were used to measure the ionic conductivity and thermal properties, respectively. READ MORE

  6. 25. MICROWAVE ASSISTED SYNTHESIS OF TITANIUM DIOXIDE ELECTRODES FOR USE IN POLYMER DSSC

    University essay from KTH/Skolan för informations- och kommunikationsteknik (ICT)

    Author : Niklas D.J. Hansen; [2014]
    Keywords : ;

    Abstract : It’s widely known that microwaves can be a useful tool when it comes to heating many different kinds of materials. It’s much less known however that compared to regular convective heating it can exhibit catalytic properties. READ MORE
