Polyacrylic and polymethacrylic acids in combination with polymers such as polyacrylamide provide the ability for controlled and sustained drug delivery since they represent pH- and temperature responsiveness. In addition, the synthesis techniques can be used to develop a higher level of supramolecular structures as the interpenetrating polymer networks – as bulk hydrogels or micro-/nanogels. They can provide the opportunity to organize and build up state-of-the-art carriers for different types of drugs thus providing ability to control their loading capacity and drug release performance. This flash review aims to summarize the efforts for synthesis of such interpenetrating polymer networks, their properties and to demonstrate the authors contributions into this field.

A binder- and carbon-free 3D Ag–Cu–S electrode for lithium-ion batteries, exhibiting excellent cycling stability defined by the “displacement” reaction with Li ions.
