Abstract:
The soft matter materials used in the conservation of cultural relics can be classed as the synthetic polymers, microemulsion, micelles, gels and inorganic colloidal nanoparticles. As protective materials, the soft matter should ensure maximum security, efficiency and durability. Meanwhile, the unexpected damage to cultural heritage should be avoided as much as possible by systematic, rational, objective methods for performance evaluation. This paper summarized the characteristic and application prospect for the soft matter of polymers, microemulsions, micelles and colloidal particles which are widely used for the protection, restoration and consolidation. Moreover, the evaluation methods for protective performance are also presented in terms of the water absorption, water vapor permeability, surface properties, mechanical properties, penetration and age resistance. Meanwhile, inspired by the special physical and chemical properties of soft matter and nanomaterials, a new challenge for soft matter used as the cleaning and consilidate materials of patinings is discussed.
