▎ 摘　　要

NOVELTY - Preparation of graphene oxide-polyurethane foaming material involves preparing oxidized graphite alkene using Hummers method, adding polyether glycol (NJ-330), foaming agent, foam stabilizer and catalyst, mixing in chamber, stirring, then adding isophorone diisocyanate and reacting. USE - Preparation of graphene oxide-polyurethane foaming material used for absorbing heavy metal ion from wastewater (claimed). ADVANTAGE - The metal efficiently and economically provides graphene oxide-polyurethane foaming material having high metal ion-absorption effect. DETAILED DESCRIPTION - An INDEPENDENT CLAIM is included for graphene oxide-polyurethane foaming material.
