This research aims to develop a dual-function preservation system for simultaneously deacidifying and reinforcing aging paper archives.
Synthesized porous calcium carbonate (P-CaCO3) using sodium dodecyl sulfate and polyvinylpyrrolidone.
Integrated cellulose nanofibrils to stabilize the suspension and enhance mechanical properties.
Applied the system to acidified aging paper samples and optimized conditions for treatment.
Achieved 22.45% increase in tensile strength and 38.42% increase in burst strength in treated paper samples.
Elevated pH from 5.82 to 8.28 and established an alkaline reserve capacity of 305 mmol/kg.
Resulted in a 17.09% increase in tear strength under optimized treatment conditions.
