Surface Energy Analysis for Study on Biomimetic Materials for Historic Stone Sculptures and Buildings

Abstract

The conservation of historic stone sculptures and buildings is receiving growing attention because of increasing bad weathering. In this paper, the surface energy analysis is applied to study the biomimetic conservation of the stone relics. The white stone surfaces were cleaned by some different organic solvents, modified by the organic template solutions with various concentrations and coated by protective films prepared through a biomimetic method. Moreover, their surface energies were tested. The surface treating technologies were optimized according to energy analysis and thus the optimal preprocessing technologies of protective materials’ preparation were determined based on the principle of heterogeneous nucleation, which is a help for the further investigation on the conservation of some stone relics.
