  1. 1. Morphological study of PS/PMMA-matrix on glass, related to vapour pressure, mass-fraction, and size

    University essay from Karlstads universitet/Institutionen för ingenjörs- och kemivetenskaper (from 2013)

    Author : Gustav Larsson; [2023]
    Keywords : organic solar cells; polymer; morphology; film; AFM;

    Abstract : The objective of this study is to observe how changing amount or ratio between dried mixes of poly-methyl-methacrylate and poly-styrene change the surface appearance, and how the results might inform future design of Organic photovoltaic cells, whom are based on polymer mixtures and heavenly dependent on the arrangement of polymers. An atomic force microscope was used on glass surfaces coated in a poly-methyl-methacrylate/poly-styrene matrix and dried from either dichloromethane or ethyl-acetate to determine surface appearance.

  3. 2. Evaluation of different block-copolymer coatings of iron oxide nanoparticles by flash nanoprecipitation

    University essay from KTH/Fiber- och polymerteknologi

    Author : Felix Bogdan; [2023]
    Keywords : Nanopartiklar; organisk katalysator; ROP; block-sampolymerer PL G A; oljesyra IONPs; Nanoparticles; organic catalyst; ROP; block-copolymers PL G A; oleic acid IONPs;

    Abstract : Nanopartiklar (NP) erbjuder unika möjligheter för medicinska tillämpningar, inklusive kontrollerad frisättning av cancerläkemedel, användning som bildkontrast vid avbildningsprocedurer eller hypertermisk behandling av cancerceller. Flash nanoprecipitation (FNP) producerar NPs för att kombinera dessa tillämpningar i en snabb, billig och skalbar beläggningsprocess. READ MORE

  4. 3. Graphene Based Aqueous Ammonium Dual-Ion Batteries

    University essay from Uppsala universitet/Strukturkemi

    Author : Arvid Sandberg; [2023]
    Keywords : Dual ion batteries; materials science; chemistry; organic polymer;

    Abstract : The global transition to renewable energy sources is placing high demands on the development of effective energy storage methods, the most prevalent being batteries. Dual-ion batteries are a new battery technology that takes advantage of the simultaneous intercalation of both cations and anions. READ MORE

  5. 4. Impact of Organic Solvent Treatments on Physical and Sensorial Properties of Knitted Fabrics.

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

    Author : Sara Isabel Zamora Lagos; [2023]
    Keywords : Innovation; Screen-printing; Knitted fabric; Polyester; Cotton; Organic Solvents; Cycle; Properties; Physical; Structure; Sensorial.;

    Abstract : Technologies that facilitate reusing and recycling printed textile products will contribute to achieving a circular textile industry. This project was done in collaboration with Vividye, a company developing a technology to create removable textile prints to be able to extend the lifespan of screen-printed textile products without affecting their quality.

  6. 5. Production of polymers from a papermills wastewater using HTC substrate. : Investigating the viability of using wastewater sludge from Skoghalls’ papermill in combination with filtrate from HTC of sewage sludge to produce biological plastic producing polymers.

    University essay from Karlstads universitet/Avdelningen för energi-, miljö- och byggteknik

    Author : Regan George; [2023]
    Keywords : PHA; HTC-substrate; Polymer;

    Abstract : Since their conception, plastics have been a dominant product due to the versatility of use, and readily available raw materials. However, the production and consumption of synthetic plastics have continued to increase over the years, leading to a significant rise in plastic waste and its associated environmental impacts, such as the detrimental effects plastic waste has on ecosystems, including the presence of toxic microplastics and risks to marine life, are becoming the focus of criticism.
