Nanocomposites of Polyhydroxyurethane with POSS Microdomains: Synthesis via Non-Isocyanate Approach, Morphologies and Reprocessing Properties

Weiming Liu et al.

Summary: In this study, a novel trifunctional POSS cyclic carbonate was synthesized and used to create nanocomposites of polyhydroxyurethane with POSS. The incorporation of POSS microdomains resulted in improved thermal and mechanical properties, while retaining the reprocessing properties of vitrimers.

Thermal, mechanical, and tribological properties of epoxy polymer/EPU blends reinforced by low concentration of octaaminophenyl POSS

Hongling Yi et al.

Summary: The inclusion of OAPOSS as reinforcement significantly enhanced the thermal stability and mechanical properties of epoxy polymer/EPU blends. The addition of EPU improved the toughness of the matrix, resulting in higher impact strength and elongation at break. The wear mechanism of OAPOSS incorporated hybrid composites involves both abrasive wear and adhesive wear.

Hydrolytic stability of polyurethane/polyhydroxyurethane hybrid adhesives

Soilikki Kotanen et al.

Summary: Polyurethane/polyhydroxyurethane (PU/PHU) hybrid materials show potential as alternatives to PU adhesives with good mechanical and adhesive properties, but are susceptible to water uptake leading to potential bond failure. After water immersion, cohesive strength of PU/PHU increases while adhesive strength decreases, requiring careful application design for optimal usage.

Trends in non-isocyanate polyurethane (NIPU) development

Alvaro Gomez-Lopez et al.

Summary: The transition towards safer and more sustainable production of polymers has led to a growing interest in non-isocyanate polyurethanes (NIPUs) as potential replacements for conventional materials. However, the challenges in directly replacing conventional polyurethanes (PUs) with NIPUs have been more difficult than initially anticipated. Despite significant academic research, the market size of NIPUs remains small, indicating a need for continued efforts to overcome limitations and promote industrial adoption.
