1. Simulations of polymer solutions displaying a lower critical solution temperature
University essay from Lunds universitet/Kemiska institutionenAbstract : Thermoresponsive polymers with a lower critical solution temperature, LCST, have attracted interest in the development of new ``smart materials'', which change properties in response to external stimuli. Polymers with an LCST near physiological temperatures are especially relevant in biomedical applications, most notably perhaps in drug delivery systems. READ MORE

2. Synthesis and characterization of amine-functionalized microgel particles and their subsequent assembly into colloidal molecule-like clusters by droplet-based microfluidics
University essay from Lunds universitet/Kemiska institutionenAbstract : The ability of thermoresponsive, amine-functionalized microgel particles to take part in microgelmicrogel inter-cross-linking has previously been reported in the literature, in connection to applications such as for example the formation of stimuli-responsive colloidal gels and colloidosomes [1]. This thesis deals with the synthesis of such thermoresponsive, cross-linkable microgels and their subsequent assembly into clusters using droplet-based microfluidics, with the goal of forming responsive colloidal molecules with well-defined valency.

3. Ion association to poly(N-isopropylacrylamide) by diffusion and electrophoretic NMR
University essay from KTH/Skolan för kemivetenskap (CHE)Abstract : PNIPAM (poly(N-Isopropylacrylamide)) is a well-known thermoresponsive polymer. Dissolved in water, it shows a structural change at 32 oC, above which the polymer folds together, and a phase separation occurs. READ MORE

4. Modification of nanofibrillated cellulose with stimuli-responsive polymers
University essay from KTH/Skolan för kemivetenskap (CHE)Abstract : 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.
