Scientists developed a high-entropy hydrogel that stiffens 760-fold when heated and softens in 28 seconds upon cooling. This ...
as well as enthalpic contact energy between nanoparticles and polymer, this is countered by the gain in conformational entropy provided by moving the linear PS chains away from the substrate and ...
Once grafted onto the MOF films, these chains form a disordered "coil" structure, known as a "high-entropy state," which is ...
