Synthesis of Zinc Stannate Microcapsules for Preparation of Flame-Retardant PVC Composites

The original Fig. 2(1-4) in the article presented smooth surface and well–dispersed morphology. Moreover, the regular shapes with sphere structure of MF/ATH/ZS microcapsule were observed in Fig. 2(5-7). After repeated experiments, we found that the new images are not consistent with the original images. In the modified images [Figure 2(1-7) below], the pure ZS particles [Fig. 2(1)] is irregular shape. Also, the ATH/ZS microcapsule [Fig. 2(2-4)] has rough surface and edges. The MF/ATH/ZS microcapsule (Fig. 2c) is irregular shape with rough surface and edges. Thus, we have made corrections and the revised images are:

The original Fig.7a showed that the surface of the pure PVC was fragile and cracked, the Fig.7b-e showed a more tight structure, and the outer surface was continuous. After repeated experiment, we found that the modified image is not consistent with the original image, the following Fig.7a,b, have lots of small holes. The Fig.7c,d showed lots of air bubbles. The Fig.7e showed tight and continuous structure. Thus, we have made corrections and the revised images are:
