Hydrogels are jelly-like materials consisting mainly of water (up to 99 wt%) and a small amount of clay mineral gelator. Hydrogel surfaces in many respects resemble to free water surfaces. In particular, they can be as smooth as water surfaces and may serve as a substrate for hydrophilic monolayers such as lipids with polar head groups. Remarkably, gel surfaces may be tilted by a few degrees out of the horizontal plane. Here, we report on a neutron reflectivity study of hydrogel surfaces with a lipid coverage.
