  1. 1. Characterisation of Poly(trimethylene carbonate) and f-BTI2g-TVTCN blends for the use in Biosensors

    University essay from KTH/Kemiteknik

    Author : Sara El Ghamri; Ed Kammeby; Herman Göransson; Arvid Stjerngren; [2023]
    Keywords : Bionedbrytbara biosensorer; Biodegradable biosenors; Organic mixed ionic–electronic conductors; Carboxyl esterase; organic electrochemical transistors; poly trimethylene carbonate ;

    Abstract : This report aims to study the degradation of poly(trimethylene carbonate) (PTMC) caused by the enzyme carboxylesterase in vitro. As well as to characterise polymer blends of f-BTI2g-TVTCN and poly(3-hydroxybutyric acid) as core components for organic electrochemical transistors (OETCs). READ MORE

    Abstract : Polyhydroxyalkanoates (PHAs) are a group of bioplastics, which are produced through microorganisms. They are accumulated in granules inside bacteria’s cell cytoplasm and serve as an energy reserve. READ MORE

  6. 5. Investigation of graphene and nanocellulose hybrid films as a barrier material in packages

    University essay from Lunds universitet/Centrum för analys och syntes

    Author : Jens Bodelsson; [2019]
    Keywords : Nanocellulose; CNF; Graphene; Barrier; Dispersion; graphene nanosheets; coating; sonication; carboxymethylated; polymer technology; polymerteknologi; Technology and Engineering;

    Abstract : In this report, hybrid films of carboxymethylated cellulose nanofibrils (CNF) and graphene nanosheets (GNs) have been prepared to evaluate if the GNs can enhance the barrier properties of the CNF films. CNF already possess great barrier properties at low relative humidity (RH) but it is drastically lowered when the RH reaches above 50% due to its strong hydrophilicity of CNF. READ MORE
