Cellulose ethers and nanoconsolidants: preliminary observations on the suitability of the use of cellulose derivatives in the synthesis of nanolime particles

Penka Girginova, Cristina Galacho
Abstract:
This communication reports the preliminary results of our ongoing research on the effect of addition of cellulose-derivatives, such as cellulose ethers, in the synthesis of calcium hydroxide (Ca(OH)2) micro-sized particles. Particles of Ca(OH)2 were synthesised without and with addition of different amounts hydroxypropyl methylcellulose (HPMC). The obtained particles were characterized with X-ray diffraction (XRD), scanning electron microscopy (SEM) and Fourier-transform infrared spectroscopy (FTIR). Our preliminary results anticipate that syntheses with addition of HPMC originated the formation of smaller and more uniform in shape and size Ca(OH)2 particles in comparison with the Ca(OH)2 particles synthesized without addition of HPMC. This study contributes to the urgent need of innovative non-toxic sustainable materials, compatible with the original artworks, with long-term efficiency and easy for application.
