Asia-Pacific Journal of Chemical Engineering, EarlyView.ABSTRACT A new type of thin‐film nanocomposite (TFN) membrane was synthesized by incorporating cellulose nanocrystals (CNCs) into a polyvinyl alcohol (PVA) top layer on a polycarbonate (PC) substrate via dip‐coating. The synthesized TFC and TFN membranes (PC/PVA TFC and PC/PVA‐CNC TFN membranes) were evaluated using contact angle measurement, field ...
