| Summary: | 碩士 === 正修科技大學 === 化工與材料工程研究所 === 100 === This study is the use semi-continuous photopolymerization of microfluidic devices, to control size and pore size of the microspheres, synthesis of porous polymer microspheres. Reaching to increase the contact area and improve the efficiency of the reaction function.
Compared with traditional emulsion polymerization, the microfluidic synthesis of porous microspheres, and better control the particle size of the microspheres, and combines the advantages of low cost and simple process.
Tthis paper to add crosslinker(EM265), photoinitiator(D1173) and porogen(DEP) in acrylic acid(AA) as the main monomer reactants. In microfluidic device according to a specific wavelength of light source, induced monomer reactants light polymerization, the formation of polymer microspheres. The use of solvents present in the polymer microspheres in porogen removal so as to form the porous polymer microspheres.
The porous polymer microspheres polarity of functional groups - carboxyl (COOH-) of acrylic acid monomers with good adsorption capacity on metal ions(Cu+2 、Mg+2 、Zn+2 、Cr+3), is an organic monomer with important adsorption removal of heavy metals, the prepared carboxyl type polymer microspheres can be used as with the application of heavy metals in waste water treatment / recycling.
Finally, using scanning electron microscopy (SEM) identification of the microspheres surface and Section as much holes, and the UV-Vis spectrometer measure porous polymer microspheres of metal ion(Cu+2 、Mg+2 、Zn+2 、Cr+3) adsorption experiments, the detection of microspheres for metal ion(Cu+2 、Mg+2 、Zn+2 、Cr+3) chelation ability.
