Pranav Krishnan et al.
Thermoset resins of dicyclopentadiene were viscosity-modified to achieve the rheology necessary for Direct Ink Writing, with the deposited ink solidified on-the-fly by frontal polymerization. This rapid modification strategy incorporated th...
Intermacromolecular Interaction Determines the Long-Ranged Force and Self-Assembly of Microgels at the Air/Water Interface [0.03%]
大分子间的相互作用决定了微凝胶在空气/水界面的长程力及其自组装行为
Wei Liu,Zuwei Zhao,Li Zhang et al.
Wei Liu et al.
We experimentally investigate the contribution of the interchain interaction to the interfacial stress and self-assembly of microgels at the air/water interface. Our results suggest that the intercorona penetrations contribute to an entropy...
