Uiformly-Sized, Molecularly Imprinted Polymers for Naproxen by Precipitation Polymerization Xuhong Jianga, Zhanmei Liub (College of Chemistry and Chemical Engineering, Zhongkai University of Agriculture and Engineering, Guangzhou 510225, Guangdong,China) aJiangxh69@163.com, bliuzhanm@21cn.com Keywords: Molecularly imprinted polymers, precipitation polymerization, microsphere Abstract:Uniformly-sized, molecularly imprinted polymers (MIPs) for (D)-naproxen have been prepared by a precipitation polymerization method using methacrylic acid (MAA) as a functional monomer and divinylbenzene (DVB) as a cross-linker in acetonitrile or a mixture of toluene and acetonitrile(1:3).
As no interfering reagent (i.e. surfactant or stabilizer) was used during polymer synthesis, the method turned out to be generally applicable to a broad range of template structures, and purification of the imprinted polymer beads was easily achieved.

The observed crystallite size ensures the well-defined crystal structure of co-doped ZnO thin films.
The augmented agglomeration observed with higher Ni doping imparts a more compact appearance to the overall structure of the thin films.
Lastly, dopants may exhibit different electronic configurations compared to Zn and O ions, leading to changes in the electronic band structure of ZnO.
