Abstract

Water-induced degradation threatens sandstone cultural relics, highlighting the need for effective protection. This study applies a nano-coating of PFDTS-modified TiO₂/SiO₂ to sandstone, optimizing PFDTS concentration, coating penetration depth, and hydrophobicity. A TiO₂-to-SiO₂ ratio of 75:25 with 80 μL of PFDTS achieved high water and oil contact angles of 152.7° and 145.7°, respectively. After 210 h of UV exposure, contact angles showed minimal reduction, confirming the coating's durability. Additionally, air permeability is preserved to maintain sandstone breathability. These findings provide valuable insights for safeguarding sandstone heritage sites against weathering.

期刊介绍： The aim of this international journal is to analyse and publicise the progress and current state of knowledge in the field of organic coatings and related materials. The Editors and the Editorial Board members will solicit both review and research papers from academic and industrial scientists who are actively engaged in research and development or, in the case of review papers, have extensive experience in the subject to be reviewed. Unsolicited manuscripts will be accepted if they meet the journal''s requirements. The journal publishes papers dealing with such subjects as: • Chemical, physical and technological properties of organic coatings and related materials • Problems and methods of preparation, manufacture and application of these materials • Performance, testing and analysis.
