FABRICATION OF ORDERED POROUS ARRAYS THROUGH in situ CONVERSION METHOD USING POLY(STYRENE-co-METHACRYLIC ACID) COPOLYMER COLLOIDAL CRYSTALS
聚（苯乙烯-co-甲基丙烯酸）胶体晶体原位反转制备孔阵列研究

Poly(styrene-co-methacrylic acid) P(S-co-MAA) copolymer colloidal crystals were transformed to ordered porous arrays by selective dissolution using toluene as solvent.The atomic force microscopy(AFM) and scanning electron microscopy(SEM) were used to characterize the structure change during sphere-pore transforming process,and the AES was used to analyze the element content variety of the colloidal spheres before and after the conversion.The polystyrene core in the P(S-co-MAA) latex nanospheres first swelle...
