Wettability and water absorption capacity: Paper surface wettability was evaluated through water contact angle (CA) measured by the static sessile drop method on a DCE -1 Kiowa goniometer. The CA values for 2.5 μL droplets were collected on ten different points for each board sample. Water absorption capacity was evaluated by Cobb method, according to Tappi Standard T-441 om-98, at 60 seconds contact time between the paper surface and water (Cobb60 Index, g/m²)
