SH-SSQ as a modifier for superior mechanical properties and improved plasticity of 3D printed PLA.

This work confirms that the use of silisequioxanes in the modification of polymeric and composite materials to change their properties is possible in the range of low modifier concentrations, not exceeding 2.5%. This study investigates the impact of (3-thiopropyl)polysilsesquioxane (SSQ-SH) on the properties of polylactide (PLA) for 3D printing.

Silsesquioxane-Doped Electrospun Nanofibrillar Membranes for Separation Systems.

In this study, a series of cage siloxanes (CS), e.g., three polyhedral oligomeric silsesquioxanes (SSQs) and one spherosilicate (SS) derivative, were applied as functional additives for the preparation of poly(lactic acid)-based (PLA) nanofibrillar membranes with an electrospinning technique utilizing an efficient spinning wire electrode setup.

Mechanical and Thermal Properties of Polylactide (PLA) Composites Modified with Mg, Fe, and Polyethylene (PE) Additives.

In this article, polylactic acid-based composites reinforced with 5% of polyethylene, iron, and magnesium powders were prepared by extrusion and compressed under the pressure of about 10 MPa and characterized. These composites were mechanically, thermally, and morphologically evaluated. It was found, compared to the pure polylactic acid (PLA), an improvement in tensile strength (both σ and YS) was obtained for the composite with the iron powder addition, while the magnesium powder slightly improved the ductility of the composite material (from 2.
