Reported herein is a chemistry experiment
integrating polymer chemistry
and instrumental analysis for the juniors majoring in chemistry. This
experiment has a different scheduling framework than traditional experiments
with a fixed lab period and schedule. The students arrange their experiment
flexibly and individually. Styrene maleic anhydride copolymer (SMA)
was used to stabilize hexadecanol emulsion, followed by microencapsulation
through in situ polymerization of formaldehyde-melamine. The obtained
microcapsules are characterized by scanning electron microscopy (SEM),
Fourier transform infrared (FT-IR) spectroscopy, differential scanning
calorimetry (DSC), and gas chromatography (GC). This experiment enables
the students to understand the concepts of polymeric surfactant, condensation
reaction, and in situ polymerization. Furthermore, this experiment
is beneficial to cultivate their practical ability of handling modern
instruments. The flexibility and versatility significantly enhance
the applicability of this experiment and the likelihood of widespread
adaptation.
