Multiscale design of hydrogel networks via hydrophilic side-chain length control
Published on 2026-06-16 by Takuma Kureha @NATURE
Abstract: Polymer Journal, Published online: 16 June 2026; doi:10.1038/s41428-026-01213-1Hydrogel networks with short and long hydrophilic ethylene oxide side chains exhibit distinct gelation behavior, mechanical deformation, nanoscale domain structures, and polymer/nanoparticle dynamics. This focus review summarizes recent studies showing how side-chain-length control governs these multiscale properties through gelation analysis, compression testing, scattering, rheology, and diffusion measurements. Thes[...]
Our summary: This review discusses how varying hydrophilic side-chain lengths in hydrogel networks affects gelation behavior and mechanical properties. It summarizes studies on the impact of side-chain length on nanoscale structures and dynamics.

The internetwork distance on the hydrogel surface increased from ~20 to 30 μm as the amount of β-CyD increased, as confirmed by SEM cross-sectional images. This trend is opposite to that observed for the homogeneously dispersed PVA-co-βCyD hydrog[...]
