▎ 摘　　要

NOVELTY - Preparing textile material comprises (i) preparing 10-25 g/l graphene oxide dispersion liquid as printing paste for single-sided printing of polypropylene needle-punched non-woven fabric, (ii) pre-baking at 80-100 degrees C after two-dip and two-roll in the cross-linking finishing solution to obtain graphene oxide printed polypropylene fabric, (iii) immersing graphene oxide printed polypropylene fabric in the reducing finishing solution, and (iv) taking out, washing de-ionized water and drying to obtain textile materials. USE - The preparing textile material is useful for photo-thermal seawater desalination (claimed). ADVANTAGE - The material: is economical and environmentally friendly, has high evaporation efficiency, high cost performance, simple operation, and can realize large-scale production and expand functional application of textiles.
