Studying amount, location and state of water in modified wood at moisture levels relevant for fungal degradation
(2020) In Proceedings IRG Annual Meeting 2020.- Abstract
- Water is an essential parameter for fungal degradation of wood, but degradation primarily occurs
at high moisture levels at water potential in the range of -4 to -0.1 MPa, which corresponds to 97-
99.9% relative humidity. At these moisture levels, water is present in the wood structure both in
and outside of cell walls. The majority of previous studies on the interaction between wood and
water for untreated as well as modified wood has, however, focused on the moisture range 0-95%
relative humidity and mainly on water in cell walls. In this paper, we give examples of how precise
conditioning of specimens using the pressure plate technique can be combined with other
experimental techniques in order to get... (More) - Water is an essential parameter for fungal degradation of wood, but degradation primarily occurs

experimental techniques in order to get information on interactions between wood and water at
humidity levels relevant for fungal degradation. We show examples of how pressure plate
conditioning can be combined with Differential Scanning Calorimetry (DSC) and Low Field
Magnetic Resonance (LFNMR) to get information not only about amount of water, but also about
location and state of water in untreated and modified wood. Further use of such combination of
techniques has potential to give valuable pieces of information on the role of water in degradation
processes for untreated as well as modified wood. (Less)
