Sr₂MgSi₂O₇:Eu²⁺, Dy³⁺ phosphor‐reinforced wood plastic composites with photoluminescence properties for 3D printing

Abstract

Combining wood plastic composites with 3D printing technology can easily manufacture parts with complex shapes and wood colors, but the single function limits their applications. In this research, Sr2MgSi2O7:Eu2+, Dy3+ phosphors/particleboard wood flour/poly (lactic acid) (SMSED/PWF/PLA) photoluminescence composites for 3D printing were successfully manufactured by melt extrusion. The water resistance and chemical structure of SMSED phosphors modified with five different types of silane coupling agents were characterized by water‐resistance test, Fourier transform infrared spectroscopy, and X‐ray diffraction. It was found that 3‐aminopropyltriethoxysilane (KH550) had the best effect on the modification of SMSED phosphors, formed a dense protective film. Afterward, the effect of KH550‐modified SMSED (KH550‐SMSED) phosphors content on the thermo‐mechanical properties of wood plastic composites was studied. The experimental results indicated that the mechanical properties and thermal stability of wood plastic composites were significantly improved, with the incorporation of KH550‐SMSED phosphors. Finally, based on SMSED/PWF/PLA composites and 3D printing technology, a safety warning model that could emit blue light in the dark and a small dinosaur artwork that could swing flexibly were prepared.

Effect of Modification and Hydrothermal Ageing on Properties of 3D-Printed Wood Flour–Poly(butylene succinate)–Poly(lactic acid) Biocomposites

“…Some changes occurred to the spectra after WF was treated with KH550. The wide band around 3300 cm −1 in WF is due to the stretching vibration of hydroxyl groups; for C-WF, however, the wide band is replaced by two peaks at around 3321 cm −1 and 3278 cm −1 , corresponding to the absorbance of hydroxyl groups from WF and amino groups from KH550 [ 35 ]. The absorbance by -OH groups was found to be weakened dramatically; this might be due to the reduction in hydroxyl groups resulting from the reaction between the -OH groups and KH550.…”
