| description | In this work at the first step calcium hydroxide nano-particles were synthesized via sono-chemical method at room temperature. At the second step aminated multi-walled carbon nano-tubes was prepared via chemical modification of surfaces of CNT. Finally modified-MWCNT and Ca(OH)2 were added to paraloid matrix by aid of ultrasonic irradiation. Paraloid-modified-MWCNT-Ca(OH)2 nanocomposite was used as a protection agent applicable in cultural heritage preservation. This nanocomposite can be used against acid rain that is destructive agent in historic monuments. One of the main advantages of paraloid as a consolidant is that it is stronger and harder than polyvinyl acetate without being extremely brittle. Nanostructures were characterized by X-ray diffraction (XRD) and scanning electron microscopy (SEM). Thermal stability behavior of paraloid filled with calcium hydroxide was investigated by thermogravimetric analysis (TGA). Our results show that the MWCNT-Ca(OH)2 nanostructure can enhance thermal stability property of the paraloid matrix. Nano-additives like a barrier slow down volatilization of paraloid chains against heat. |
