Performance Study of Graphene Oxide as an Antierosion Coating for Ornamental and Heritage Dolostone

Concern for the perpetuation of stone monuments is deeply ingrained in humans; however, despite attempts made this field, there still a great deal effort needed to bring about advancements conservation ornamental stone. Erosive agents, such as rain, extreme temperatures, and chemical biological threaten our heritage gradually wear away buildings, sculptures, other found all around world. Limestone dolostone have been widely used throughout history, given their ease extraction workability. Nevertheless, these properties make them particularly vulnerable aforementioned erosive which main solution at present costly time-consuming restoration. Given scarcity effective durable agents prevent deterioration stones, graphene oxide (GO) has recently shown impressive effectiveness task, work will further explore viability GO protective coating monumental dolostone. For purpose, sprayed over surfaces by water dispersion with no adjuvants. The performance assessed terms thermal stress, optical inspection (structured light 3D scanner), colorimetry, leachate analysis, electron microscopy. results show that spray-coated creates highly barrier without altering aesthetic qualities.
