An increase in the water composition reduced the crystallization degree of AN units, resulting in a variety of the nanoparticle morphology such as the increased particle size, the reduced projection size, the increased projection number, and the decreased inter-projection distance. As shown in Fig. 1(a) , nanoparticles prepared in the solvent with a water composition of 20 vol% had projection coronas similar to a coronavirus in morphology. On the other hand, nanoparticles with projection coronas were not formed when the water composition was higher than 50 vol% since the dispersion system was not created during polymerization.	./cache/cord-350876-e7le4oh5.txt	./txt/cord-350876-e7le4oh5.txt
