Abstract Recent years have seen increasing interest in the construction of nanoscopically layered materials involving aqueous‐based sequential assembly polymers on solid substrates. In booming research area layer‐by‐layer (LbL) oppositely charged polymers, self‐assembly driven by hydrogen bond formation emerges as a powerful technique. Hydrogen‐bonded (HB) LbL open new opportunities for films, which are more difficult to produce than their electrostatically assembled counterparts. Specifically, properties associated with HB include: 1) ease producing films responsive environmental pH at mild values, 2) numerous possibilities converting into single‐ or two‐component ultrathin hydrogel materials, and 3) inclusion low glass transition temperatures (e.g., poly(ethylene oxide)) within films. These can lead applications such pH‐ and/or temperature‐responsive drug delivery systems, tunable mechanical properties, release dissolvable under physiological conditions, proton‐exchange membranes fuel cells. this report, we discuss recent developments synthesis based assembly, study structure–property relationships, prospective constructs biotechnology biomedicine.
