highly viscous due to the high molecular weight of the poly-
mer and the presence of strong hydrogen-bonding between
PVA chains, as well as between PVA chains and water mole-
cules. Therefore, during filtration, the entangled PVA chains
gradually blocked the nanopores of polycarbonate membrane
to some extent. As a result, the filtration rate was significantly
slowed down, which further promoted the aggregation of PVA
chains to form a compact film.
