Characterization of compressed bacterial cellulose nanopaper film after exposure to dry and humid conditions

This work investigates the effects of two different levels of humidity (RH 50% and 75%) on the characterizations of compressed bacterial cellulose nanopaper film. The film was prepared with different heat treatments; compression at 25 °C for 72 h and then at 100 °C for 24, 72 or 120 h. Maximum tensi...
