The properties of many polymers are affected by hydrogen bonds within and/or between the chains.  Prominent examples include [[cellulose]] and its derived fibers, such as [[cotton]] and [[flax]]. In [[nylon]], hydrogen bonds between [[carbonyl]] and the [[amide]] N''H'' effectively link adjacent chains, which gives the material mechanical strength. Hydrogen bonds also affect the [[aramid]] [[fibre]], where hydrogen bonds stabilize the linear chains laterally. The chain axes are aligned along the fibre axis, making the fibres extremely stiff and strong. Hydrogen-bond networks make both polymers sensitive to [[humidity]] levels in the atmosphere because water molecules can diffuse into the surface and disrupt the network. Some polymers are more sensitive than others. Thus [[nylon]]s are more sensitive than [[aramid]]s, and [[nylon 6]] more sensitive than [[nylon-11]].{{cn|date=June 2023}}
