Abstract
In this study, we synthesized polymethyl methacrylate cross-linked microspheres and functionalized the surface of the microspheres with amine groups, and discussed the effect of functionalization and the change of the surface morphology of the microspheres. This research uses 1:2 metal composite acid dye to dye self-synthesized microspheres with uniform particle size, and successfully prepares black polymethyl methacrylate cross-linked microspheres, which are applied to spacer microspheres.
Highlights
A polymer sphere is a substance in which a plurality of polymer chains are wound and stacked on each other and are present in a spherical structure
In the presence of the sphere, the sphere is loose, because the monomer has not grown to a certain extent after the formation of the primary nucleus, and its properties are biased toward the oligomer which is soluble in the medium, and the stability in the system is not sufficient
ΔE 42.66 44.39 60.97 70.87 it is inferred that the number of cationized amine groups on the surface of the microspheres is higher at pH 4, so that more dyed seats can be combined with the acid dye, but the pH can be found corresponding to Table 3
Summary
A polymer sphere is a substance in which a plurality of polymer chains are wound and stacked on each other and are present in a spherical structure. Since the liquid crystal layer has a uniform thickness and a load-bearing capacity, the spacer polymer microspheres need a high particle size uniformity, and the average particle diameter is between 3 and 7 micrometers. It has elasticity, high mechanical strength, smooth surface, high cleanliness and extremely low metal impurities. Polymethyl methacrylate with excellent transparency and chemical stability is the current mainstream spacer microsphere material, and reference functionalized microsphere literature. The problem is that the crosslinked structure gives the microspheres excellent mechanical properties
