In this work, we succeeded in direct visualization of the network structure of synthetic hydrogels with TEM by developing a novel staining and network fixation method. Such a direct visualization had not been carried out because sample preparation and obtaining sufficient contrast are challenging for these soft materials. TEM images revealed robust heterogeneous network architectures at mesh size scale and defects at micro-scale. TEM images also revealed the presence of abundant dangling chains on the surface of the hydrogel network. The real space structural information provides a comprehensive perspective that links bulk properties with a nanoscale network structure, including fracture, adhesion, sliding friction, and lubrication. The presented method has the potential to advance the field.
