Aiming at the lack of cultivating students' scientific research thinking in polymer chemistry experiment teaching
this study set the network structure regulation and properties of amine-cured epoxy resin-based shape memory polymers as a comprehensive experiment. Epoxy resin and polyether amine were used as raw materials to synthesize an epoxy resin-based shape memory polymer with a shape memory effect through body three-dimensional polycondensation. Crosslinking density
glass transition
storage modulus
loss factor and shape memory properties of materials were investigated using gel content
differential scanning calorimetry
dynamic thermomechanical analysis and creative experiments. Guide students to establish a scientific research thinking mode of “chemistry → structure → performance → function” for polymer materials
and connect important theories of polymer chemistry and physics in this progressive relationship
to provide training for scientific research thinking and innovation consciousness. Through the interesting macroscopic shape memory effect of “deformation → fixation → recovery”
students can perceive the microscopic glass transition and entropy elastic process
and their interest and innovative awareness in scientific research are fostered by interesting experimental phenomena and sensory stimulation.
