| description | To improve the quality of deuterated polystyrene (DPS) shells, the synthesis and
purification of DPS as well as the fabrication of DPS shells are investigated. The
molecular weight and molecular weight distribution, measured by GPC-MALLS, are about 350
kg mol-1 and less than 2.0, respectively. The results of TG and GC-MS indicate
that the residual solvent is almost completely removed. DPS shells with ∼ 300 μm –2500 μm
diameter and ∼10 μm–100 μm wall thickness are successfully prepared by a microfluidic
device. The monodispersity of the diameter is much better than that of the wall thickness
in a batch of DPS shells. The vacuoles can be suppressed by both reducing hydrophilic
residues in DPS and adding some salts into the outer water phase (W2). The defects
appearing during the drying process decrease by heat treatment, ethanol exchange, and
lowered drying temperature. The results presented in this work not only provide guidelines
for the preparation of DPS shells of better quality, but also indicate challenges for the
future. |
