AbstractHigh flame retardancy with significant suppression of toxic smoke and melt-dripping are challenging issues associated with flame-retardant thermoplastic polyurethane (TPU). To address these issues, in this work, graphene (Gr) was used as an effective two-dimensional smoke-toxicity suppressant with loadings less than 1 wt%, in combination with two efficient intumescent flame retardant (IFR) systems reported in our previous works.

%VBur index and steric maps: from predictive catalysis to machine learning Steric indices are parameters used in chemistry to describe the spatial arrangement of atoms or groups of atoms in molecules. They are important in determining the reactivity, stability, and physical properties of chemical compounds.

AbstractIn this paper, for the first time, the role of manufacturing parameters of fused deposition modeling (FDM) on the shape memory effect (SME) is investigated by design of experiments. PLA-TPU blend with a weight composition of 30:70% is processed by melt mixing and then extruded into 1.75 mm filaments for 3D printing via FDM. SEM images reveal that TPU droplets are distributed in the PLA matrix, and the immiscible matrix-droplet morphology is evident.
