2.2.3. Coating
Different amounts of the resulting composites for mulations were coated onto the surface of the handsheets (60 g/m2) made in lab. The solvent was allowed to evaporate at room temperature by putting the coated handsheets in a fume hood for at least 24 h,and the resulting products were dried in a vacuum oven at 50◦C for 48 h to remove the residual solvent (Hossain et al., 2012).
