“…In addition, these traditional materials can be easily cleaned out as compared to the organic polymers. Some findings regarding the application of a crude biomimetic protective film on stone buildings and sculptures have also been reported (Liu et al, 2006b). These findings could not only lead to the development of new protective methods or ideas concerning stone conservation, but also contribute toward new researches into biomineralisation or biocontrolled processes.…”

“…Coating stone is an effective way to protect stone-built cultural relics from damage [10]. The coating materials can be divided into two categories: organic and inorganic [11]. Organic coating materials have demonstrated excellent hydrophobicity, weather resistance, acid resistance, and salt corrosion resistance [12][13][14]; however, they can easily turn yellow, age, and show other negative effects on cultural heritage, thus reducing the protection timespan [15].…”

Coating materials can effectively protect stone-built cultural heritage and, as such, research into coating materials has gained comprehensive attention from researchers. The aim of this work is to prepare a TiO 2 -modified sol coating material (TSCM) and study its protective effects on stone-built cultural heritage. TSCM and pure TiO 2 sol (p-sol, unmodified; for comparison) were applied evenly over the entire surface of stone samples. The prepared stone samples included untreated stone, stone treated with pure sol, and stone treated with TSCM. The protective effects of TSCM were evaluated by water absorption, water vapor permeability, acid resistance, and weather resistance experiments. The results show that stone treated with TSCM has excellent water absorption and water vapor permeability, strong acid resistance, and good weather resistance, compared with untreated stone or stone treated with p-sol. The acid resistance of stone treated by TSCM was 1.75 times higher than that treated with traditional coating materials. The weather resistance cycle number of stone treated by TSCM was four times higher than that treated with organic protective materials. These findings are expected to provide useful suggestions for the protection of stone-built cultural heritage.Coatings 2020, 10, 179 2 of 11 or added to acrylic polymers [22][23][24], but they could be easily removed from the coating surface owing to weak bonding [25][26][27]. In order to avoid the loss of TiO 2 nanoparticles, some researchers have proposed to composite TiO 2 nanoparticles into a SiO 2 -sol [28], which can enhance its photocatalytic activity when applied to a building. To the best of our knowledge, there have been no scientific studies about compositing TiO 2 nanoparticles into a TiO 2 -sol for the protection of stone-built cultural heritage. More importantly, the method presented in the work of [28] provides us with valuable suggestions about the protection of stone-built cultural heritage. Hence, it is necessary to investigate a modified TiO 2 -sol with significant protective effect on stone-built cultural heritage.The aim of this paper is to prepare a TiO 2 -modified sol coating material (TSCM) that is capable of protecting stone-built cultural heritage. Analyses of the composition and microscopic morphology of TSCM were conducted using X-ray diffraction (XRD) and scanning electron microscopy (SEM). Some experiments were conducted to evaluate the protective effects of TSCM, in terms of wettability, weather resistance, and acid resistance. The results suggest that TSCM has excellent water absorption, water vapor permeability, acid resistance, and weather resistance. The study, therefore, provides a new method for the protection of stone-built cultural heritage.

“…The majority of materials that have been tried as stone conservation materials have been organic polymers [3,4], but several inorganic materials deserve a particular mention, as their mode of operation is rather different. Among them, biomimetic or biocontrolled protective materials have been represented as a new prospect in stone conservation because of their unique featuresuniform size, novel crystal morphology, specific crystallographic orientation, light weight, mechanical robustness and unique functions, as well as compatibility [5]. By comparison, these organic materials, including epoxies, acrylics, alkoxysilanes, silicones and fluorine-containing polymers, have some inadequacies and defects: shorter life, poorer compatibility, and change of the face of the treated stones.…”

The conservation of historic stone buildings and sculptures is recently receiving growing attention and becoming a focus of research. However, it is difficult to estimate the effects of stone conservation, especially consolidating treatments. In this work, some biomimetic materials for stone conservation were prepared. The interaction between the protective materials and stone substrate was researched by testing their surface energy. Some thermodynamic parameters, including interfacial tension (γ fm ) and work of adhesion (W a ), were calculated. The effects of interaction between the materials and substrate on reinforcement properties were investigated. The results show that the strength of materials' adhesion to a solid surface could be better estimated from the value of W a /γ fm . It is helpful not only to indirectly determine the mechanical properties of the reinforcing agent but also to design some materials for stone conservation on a purpose not on a rather hit-or-miss basis.
