Wood polymer interactions with ions and macroions

Online February 24, 13:00 – 16:45 CET

The interaction of wood polymers with ions and polyelectrolytes is critical for developing novel materials for the future and refining existing products and processes. We welcome you to the online mini-conference titled ‘Wood polymer interactions with ions and macroions’ on 24th February 2022 from 13:00 – 16:45 CET.

The event is jointly organized by Chalmers University of Technology, AvanCell, Södra and Treesearch.

The following day, Vishnu Arumughan will defend his PhD thesis, in which he will discuss how negatively charged carboxymethylcellulose adsorbs to a slightly negatively charged cellulose surface.


13.00 – 13.15
