“…All this together determines their high penetrating ability into porous structures and the significant perspectives including those regarding the target of crushed stone impregnation. The effectiveness of this approach was many times confirmed both by multiple research works [6]- [13] and industrial realizations [7] [9] [14]- [17].…”

“…These unique and versatile features make scCO 2 a perfect candidate for application in the heritage conservation field. Despite its very limited use in this field, liquid and supercritical CO 2 have been tested in various treatments on a range of different materials, such as drying of waterlogged wood [ 48 , 49 ]; removal of various pesticides from objects in ethnographic collections comprising wood, leather, and textiles [ 50 , 51 ]; deacidification of paper-based objects [ 52 , 53 , 54 , 55 , 56 , 57 ]; and cleaning and disinfection of paper [ 58 ] and textiles [ 59 , 60 , 61 , 62 , 63 ].…”

Surface cleaning of plastic materials of historical value can be challenging due to the high risk of inducing detrimental effects and visual alterations. As a result, recent studies have focused on researching new approaches that might reduce the associated hazards and, at the same time, minimize the environmental impact by employing biodegradable and green materials. In this context, the present work investigates the effects and potential suitability of dense carbon dioxide (CO2) as an alternative and green solvent for cleaning plastic materials of historical value. The results of extensive trials with CO2 in different phases (supercritical, liquid, and vapor) and under various conditions (pressure, temperature, exposure, and depressurization time) are reported for new, transparent, thick poly(methyl methacrylate) (PMMA) samples. The impact of CO2 on the weight, the appearance of the samples (dimensions, color, gloss, and surface texture), and modifications to their physicochemical and mechanical properties were monitored via a multi-analytical approach that included optical microscopy, Raman and attenuated total reflection Fourier transform infrared (ATR-FTIR) spectroscopies, and micro-indentation (Vickers hardness). Results showed that CO2 induced undesirable and irreversible changes in PMMA samples (i.e., formation of fractures and stress-induced cracking, drastic decrease in the surface hardness of the samples), independent of the conditions used (i.e., temperature, pressure, CO2 phase, and exposure time).
