Abstract:

Glass microsphere was modified by the surface in situ polymerization reaction of dopamine. The chemical composition of the glass microsphere before and after modification was characterized by X-ray photoelectron spectroscopy(XPS) and Fouried transform infrared spectroscopy(FTIR), its thermal stability was tested by thermogravimetry(TG) and its morphology was observed by transmission electron microscope(TEM) and scanning electron microscope(SEM); the effects of the modified glass microsphere on the thermal, mechanical and shape memory properties of the shape memory composite polycaprolactone and polyurethane(PCL/TPU) were investigated. The results show that the surface-coated polydopamine glass microsphere(PHGM) was successfully prepared, and the addition of modified glass microsphere not only enhanced the mechanical properties of the materials(the tensile strength increased to 53.3 MPa and the Young’s modulus increased to 178.4 MPa at 3% of modified glass microsphere), but also imparted excellent photothermal effects to the materials. When the composites were exposed to 808 nm near infrared(NIR) light, they can reach their switching temperature and return to their permanent shape within a short time (7 s).

Key words: Polydopamine, Glass microsphere, Shape memory composites, Photothermal effect
