High-strength and recyclable hydroplastic films from hydrophobic cellulose nanofibers produced via deep eutectic solvents

•Hydrophobic cellulose nanofibers were obtained through DES and nanofibrillation.•Hydroplastic films were fabricated by vacuum filtration from hydrophobic cellulose nanofibers.•The hydroplastic films showed good hydrophobicity and mechanical performance.•The films could be converted into 3D shapes by hydrosetting, kirigami, origami and embossing method.•The recyclable use of hydrophobic cellulose nanofiber films was achieved.
