1. Ion specific effects in polymer conformation
University essay from KTH/Tillämpad fysikalisk kemiAbstract : It is well known that ions affect polymers in specific ways not solely based on electric charge, usually referred to as the Hoffmeister effect or ion specific effects. Poly(N-isopropylacrylamid) (PNIPAM) is a thermosensitive polymer with a LCST at 32℃. 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
