1. Ion specific effects in polymer conformation
Kandidat-uppsats, KTH/Tillämpad fysikalisk kemiSammanfattning : 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℃. LÄS MER
2. Simulations of polymer solutions displaying a lower critical solution temperature
Kandidat-uppsats, Lunds universitet/Kemiska institutionenSammanfattning : 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. LÄS MER
3. Ion association to poly(N-isopropylacrylamide) by diffusion and electrophoretic NMR
Master-uppsats, KTH/Skolan för kemivetenskap (CHE)Sammanfattning : 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. LÄS MER
4. Microgels at ultrahigh densities : a small angle neutron scattering study
Master-uppsats, Lunds universitet/Kemiska institutionenSammanfattning : Populärvetenskaplig sammanfattning Microgelpartiklar är runda partiklar som har förmågan att ändra storlek beroende på olika yttre påverkan. I detta projekt har vi tittat på partiklar som blir upp till 10 gånger mindre när temperaturen höjs från 15˚C till 39˚C. LÄS MER
5. Modification of nanofibrillated cellulose with stimuli-responsive polymers
Master-uppsats, KTH/Skolan för kemivetenskap (CHE)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
