Description

上記ナノペーパーの形成後、液体収容容器１６に水以外の極性溶媒を投入し、吸引装置２０によりフィルター１８を介して水以外の極性溶媒を吸引する（溶媒処理工程）。この際の吸引の条件は、大気圧より低い圧力で、１〜１０分程度の吸引である。また、極性溶媒の使用量は、ナノセルロースの質量に対して８００〜１００００倍の質量とする。このように、極性溶媒をナノセルロース集合体（ナノペーパー）に通過させることによりナノペーパーを溶媒処理する。なお、溶媒処理工程は、１回に限らず、複数回実施してもよい。水より表面張力が小さい溶媒により処理することにより、乾燥中に作用するナノセルロースのファイバー間の引付け力を弱め間隙を詰まりにくくする（ナノセルロースファイバーのパッキングを抑制する）ことができる。このため、光還元工程において、ナノペーパー内部に吸着された酸化グラフェンの受光面積が増加して光還元効果を向上することができる。 After the nanopaper is formed, a polar solvent other than water is introduced into the liquid container 16 and the polar solvent other than water is sucked through the filter 18 by the suction device 20 (solvent treatment step). The suction condition at this time is a suction of about 1 to 10 minutes at a pressure lower than the atmospheric pressure. Moreover, the usage-amount of a polar solvent shall be 800-10000 times the mass with respect to the mass of nanocellulose. Thus, the nanopaper is subjected to solvent treatment by passing the polar solvent through the nanocellulose aggregate (nanopaper). The solvent treatment step is not limited to once, and may be performed a plurality of times. By treating with a solvent having a surface tension smaller than that of water, it is possible to weaken the attractive force between the nanocellulose fibers acting during drying and to prevent clogging of the gaps (inhibition of packing of the nanocellulose fibers). For this reason, in the photoreduction process, the light receiving area of the graphene oxide adsorbed inside the nanopaper is increased, and the photoreduction effect can be improved.
