Polymer networks containing consist of long polymer linked together using crosslinking points. Introduction of dynamic linkers, such as non-covalent or dynamic covalent linkers into a polymer material can give materials with properties such as self-healing, increased toughness and shape memory characteristics. However, there is a delicate tradeoff between desirable dynamic characteristics and also undesirable mechanical instability under load or susceptibility to creep. Therefore, designing dynamic linkers with optimized for dynamic character and performance under ambient conditions is critical to applications of these materials. This talk will focus on polymer materials that contain both dynamic covalent and dynamic non-covalent bonds in a single material. This can lead to a synergy of dynamic character from the fast exchanging bond and stability from the slow exchanging bond. Polymers architecture is a further tool that can be used to enhance and tune material properties. In particular different dynamic covalent chemistries are explored and enhanced by the introduction of hydrogen bonding units into the polymer material.<br/>
