Abstract
C.I. Pigment Red 48 : 2 (P.R.48 : 2) and C.I. Pigment Red 57 : 1 (P.R.57 : 1) composite particles encapsulated with three kinds of polyethylene (PE), which had different molecular chain structure, were prepared by dispersion polymerisation method. The modified pigments were characterised by Fourier transform infrared spectroscopy (FTIR), scanning electron microscope (SEM), UV–Vis spectroscopy and chroma. The modified particles were dispersed in Isopar L : C2Cl4 = 1 : 1 and then successfully incorporated in an electrophoretic display cell, and P.R.48 : 2/high-density polyethylene (HDPE) particles, which had electron-withdrawing groups and coating materials with high crystallinity and without short-chain branches, had the best properties and their highest contrast ratio on the same device was found to be 2.67, which was better than those of pigments modified with others PE.
