NOVELTY - Preparation of graphene oxide/calcium silicate nanowire composite material involves adding 8-12 ml 1-3 mg/ml graphene oxide solution into a 50 ml beaker, magnetically or mechanically stirring, adding 3-8 ml 0.1-1 mol/L calcium nitrate tetrahydrate solution, and ultrasonically crushing for 3-5 minutes; adding 3-8 ml 0.1-1 mol/L sodium metasilicate nonahydrate solution, and ultrasonically crushing for 3-5 minutes; and transferring to hydrothermal reaction kettle, reacting for 12-36 hours at 160-220 degrees C, taking out, and naturally cooling to room temperature. USE - Method for preparing graphene oxide/calcium silicate nanowire composite material (claimed). DETAILED DESCRIPTION - Preparation of graphene oxide/calcium silicate nanowire composite material comprises adding 8-12 ml 1-3 mg/ml graphene oxide solution into a 50 ml beaker, magnetically or mechanically stirring, adding 3-8 ml 0.1-1 mol/L calcium nitrate tetrahydrate solution using peristaltic pump or micro-injection pump, and ultrasonically crushing for 3-5 minutes; adding 3-8 ml 0.1-1 mol/L sodium metasilicate nonahydrate solution using peristaltic pump or a micro-injection pump, and ultrasonically crushing for 3-5 minutes; transferring to hydrothermal reaction kettle, reacting for 12-36 hours at 160-220 degrees C, taking out, naturally cooling to room temperature, and centrifugally washing with water for 3-5 times; and freeze-drying at - 50 degrees C to - 80 degrees C.
