The 11th ECNP International Conference on Nanostructured Polymers and Nanocomposites, originally planned for 2020 and postponed due to the pandemic, and next, due to the war in Ukraine, will be finally organized in 2023. The tradition of this conference dates back to 2004 and stems from the Network of Excellence NANOFUN-POLY and the established European Center for Nanostructured Polymers (ECNP). The ECNP conference visited Dresden,  Lyon, Corfu, Paris, Madrid, Prague, Rome, and now it is time for Lodz.
