Reinforcement and Deacidification for a Textile Scroll Painting (AD 1881) Using the CNF and MgO Suspensions.

As shown in Table 2 , the pH of model samples treated with 0.6% CNF suspension (denoted as the CNF sample in the subsequent content) shows an increasing trend after treatment with nanosized MgO with a series of concentrations from 0.01 to 0.3%.

The transmittance of CNF films was also explored, showing a decreasing trend with an increase in concentrations of CNF suspensions in the range of the visible spectrum ( Figure 2 a), as CNF nanoparticles show a white color and are not transparent.
