Superficial Optimization of the Microcapsule

To solve the gelatin and gum Arabic electronic ink microcapsules' problems of thin shells,easy to break,and having poor mechanical properties,the above microcapsules were coated by urea-formaldehyde polymer and double-shell microcapsules were obtained.The surface morphology of the microcapsules was observed by means of Metallurgical Microscopy,with the dispersion particle size of the microcapsules being measured by the Laser Particle Size Analyzer,the microcapsules' denseness being tested by a UV-Vis spectrophotometer,and the mechanical intensity being measured by the Microcomputer Control Omnipotence Test Machine.It revealed that the microcapsules,prepared by using this method,showed a regular shape;and the size of the microcapsules were increased.Additionally,both the hermetization property and mechanical intensity of the microcapsules were improved.
