“…By knowing n mer (α) we can further approximate the polymer volume fraction, which allows us to identify physically meaningful values of α and K. Using the water profile (Fig. 3) we extract the excluded volume per monomer as V ex,mer = 0.167 nm 3 and assume the BIS' volume to scale with the number of heavy atoms (without hydrogens) compared to a PNIPAM monomer (11. vs. 8), yielding V ex,xlink = 0.230 nm 3 . The excluded volume in one unit cell is then v ex = 8V ex,xlink + n mer (α)V ex,mer and the 2.…”

“…Responsive polymers have increasingly gained attention in many research fields due to their ability to reversibly adapt to external stimuli such as temperature, osmotic pressure, or pH. Various types and shapes at different length scales have been designed, providing various possibilities for applications, 1,2 such as solute uptake, transport 3 and release, 4,5 sensors, 6 intelligent coatings, switchable catalysis, 7,8 etc. To structurally stabilize and fine-tune properties and function, polymer architectures are often E-mail: joachim.dzubiella@physik.uni-freiburg.de equipped with chemical cross-linkers covalently interconnecting the chains, 9 which are then referred to as hydrogels.…”
