Synthesis of P, N and Si-containing waterborne polyurethane with excellent flame retardant, alkali resistance and flexibility via one-step synthetic approach

Lian Feng et al.

Summary: A flame retardant waterborne polyurethane with phosphorus, nitrogen and silicon units (P-N-Si-WPU) was successfully synthesized using a one-step approach. P-N-Si-WPU showed higher limiting oxygen index value and lower peak heat release rate compared to pure waterborne polyurethane. The flame retardant mechanism of P-N-Si-WPU was mainly gas phase flame retardant and condensed phase flame retardant, enhanced by the formation of a thermally stable char layer.

Henghui Deng et al.

Summary: In this study, a bio-based waterborne polyurethane (WPU) with anti-ultraviolet, corrosion resistance and excellent mechanical properties was designed and prepared using sorbitan monooleate (SP) and castor oil as raw materials.

Simultaneously Toughening and Stiffening Elastomers with Octuple Hydrogen Bonding

Yizhi Zhuo et al.

Summary: A transparent unfilled elastomer with enhanced toughness and stiffness is achieved by incorporating ultrastrong, reversible, and sacrificial octuple hydrogen bonding (HB). The homogeneous network structure distributes stress evenly to each polymer chain, enhancing stretchability and delaying fracture. Strong HBs and corresponding nanodomains enhance stiffness by restricting network mobility, while simultaneously improving toughness by dissipating energy during configuration transformation.
