“…Polymeric hollow microspheres have important applications in energy storage, microreactors, biopharmaceuticals, catalysis, etc., due to their unique structure. [1][2][3][4][5][6] The most widely studied microspheres include polystyrene, polymethyl methacrylate, polylactic acid, polyethylene glycol, and polycaprolactone microspheres. [7][8][9][10][11][12][13] However, they are difficult to meet the usage demands in harsh environments, such as high temperature, radiation and alternating electric field environments, etc., due to their molecular structures and functional group types.…”
