Special Issue Information

Dear Colleagues,

Three-dimensional (3D) printing, also known as additive manufacturing, makes it possible to accelerate product prototyping and fabricate 3D parts with complex structures. Three-dimensional printing technology has been developed quickly in recent years. Three-dimensional printing provides a new fabrication method for functional polymer matrix composites. This Special Issue of Polymers is dedicated to “Physicomechanical Properties and Application of 3D-Printed Functional Polymer Matrix Composites”. The topics of interest in this Special Issue include but are not limited to novel functional polymer matrix composites prepared by 3D printing; the effects of printing parameters on the physicomechanical properties of 3D-printed functional polymer composites; mechanical, thermal, dynamic thermal, electrical, flame-retardant, biodegradable, and other properties of 3D-printed functional polymer matrix composites; the relationship between the structures and properties of 3D-printed functional polymer composites; engineering applications and case studies of 3D-printed functional polymer matrix composites; and the theoretical simulation of the structure of 3D-printed functional polymer matrix composites.

Abstract
Wood flour–poly(butylene succinate)–poly(lactic acid) biocomposite samples were prepared by fused-deposition-molding 3D-printing technology, and modifications with glycerol and a silane coupling agent (KH550) were carried out. The samples were then hydrothermally aged. Modification with glycerol and KH550 enhanced the hydrophilicity of the samples and [...] Read more.
Wood flour–poly(butylene succinate)–poly(lactic acid) biocomposite samples were prepared by fused-deposition-molding 3D-printing technology, and modifications with glycerol and a silane coupling agent (KH550) were carried out. The samples were then hydrothermally aged. Modification with glycerol and KH550 enhanced the hydrophilicity of the samples and increased their tensile strength. Hydrothermal aging clearly whitened the surfaces of all the samples and made them more hydrophobic. Meanwhile, their tensile properties and thermal stability became poor; a higher hydrothermal aging temperature affected the mechanical properties more negatively. The modified samples turned out to be more resistant to the hydrothermal aging, and modification with KH550 could improve the anti-hydrothermal aging properties of the samples better than that with glycerol, where the tensile properties and the cross-sectional morphologies of the fractured specimens were concerned. Generally, the effects of hydrothermal aging temperature on the physico-mechanical properties of the printed specimens were greater than those by hydrothermal aging time. Full article
