For the first time, a composite from polycrystals of KH2PO4 (KDP) with a filler of cellulose nanoparticles (CNP) was prepared to investigate the influence of cellulose on domain-wall freezing and ferroelectricity of KDP. The extrapolation of experimental data using Vogel–Fulcher law demonstrated a higher temperature of domain-wall freezing in KDP/CNP composite in comparison with pure KDP. In addition, the impact of CNP led to the expansion of ferroelectric phase in KDP and the red-shift of relaxation frequencies. Besides, the deformation of P–E hysteresis loops with the increase in coercive field as well as the decrease in saturated and remnant polarization was also detected.
