Analysis of the microcapsule structure based on machine learning algorithm

Abstract: For the microcapsules preparation process, the mechanism is estimated by structure reformation during the preparation process since diameter and wall thickness drastically changed. Microstructures are recently studied by machine learning techniques. The Hough transformation algorithm is used by other researchers for the preparation of the microcapsules but it is difficult to determine the mechanism by using only a diameter change of the microcapsules. Therefore, one additional way to establish the mechanism is… Show more

“…The preparation conditions of the S/O suspension and the S/O/W emulsion were the same as in our previous work [4]. The S/O/W emulsion was stirred, as demonstrated in a previous paper [1,5,6], at 370 rpm, with the continuous evacuation of solvent vapor at 7.2 × 10 2 mmHg and 313 K for 8 h. The microcapsules were separated with a vacuum pump. In order to prepare the microcapsule containing TOA, 20% of TOA in the polystyrene wall was added to the organic phase.…”

“…The morphologies of the microcapsules were observed by digital microscopy (DM, VHX-600 system, KEYENCE Corp.). The microcapsule distributions were characterized via the Hough transform which is available in our previous work [5]. The microcapsule sampling was directly from a reactor by using a micropipette.…”

“…e Hough transform, histograms of oriented gradients (HOG), and support vector machine (SVM) are the main algorithms in image segmentation, feature extraction, and classi cation sections, respectively, in the developed MLA. A more comprehensive information on the pipeline of structure and diameter detection is available in our previous work (Batchuluun et al, 2021). For thickness measurements, the microcapsule sample were mixed in glue media at 373 K. In addition, 179 images with 3,200×2,400 pixels were used with 400 times magnication.…”
