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

    Master-uppsats, KTH/Fiber- och polymerteknologi

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

    Sammanfattning : 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. LÄS MER

  3. 2. Design of solvent vapor annealing tool and study of kinetics of selfassembly of block copolymers for nano-lithography

    Master-uppsats, Lunds universitet/Fasta tillståndets fysik; Lunds universitet/Fysiska institutionen

    Författare :Chujun Wang; [2020]
    Nyckelord :Physics and Astronomy;

    Sammanfattning : Block copolymer lithography is a very promising candidate for nanoscale fabrication and is economically viable. It provides a high resolution, inexpensive, and straightforward approach to nano-size patterning. In this thesis, fundamental concepts and theories of block copolymer lithography are introduced.

  4. 3. Factors affecting the properties and behaviour of blockcopolymer micelles

    Uppsats för yrkesexamina på avancerad nivå, Uppsala universitet/Institutionen för kemi - BMC

    Författare :Jakob Ovrén; [2017]
    Nyckelord :;

    Sammanfattning : Polymers are of fundamental importance to our society and can befound in many different products. Block copolymers are polymerswhich are divided up into distinct blocks of two or more differentmonomers. Block copolymers with regions of difference in polarityare capable of self assembling into ordered systems. LÄS MER

  5. 4. Depth-sensitive time-of-flight small-angle neutron scattering

    L3-uppsats, Materialfysik

    Författare :Jörg Herbel; [2013]
    Nyckelord :;

    Sammanfattning : Block copolymers are quiet imported in industry. A detailed knowledge of the solid-liquid boundary conditions for surface effects in their aqueous solutions supports the development of smart coatings or the understanding of the folding of proteins in the vicinity of cell membranes.

  7. 5. Modification of nanofibrillated cellulose with stimuli-responsive polymers

    Master-uppsats, KTH/Skolan för kemivetenskap (CHE)

    Författare :Carmen Cobo Sanchez; [2012]
    Nyckelord :thermoresponsive; nanofibrillated cellulose; biocomposites; block-copolymer; stimuliresponsive;

    Sammanfattning : Research of new sustainable and low cost materials, such as cellulose, is of high interest. Modifications of the cellulose can be performed in order to create a “smart” material which responds to external stimuli, such as variations in pH and temperature, by changing its properties. LÄS MER
