A Visualization Method to Investigate the Mechanism of Cell Nucleation and Growth in High-Pressure Foam Injection Molding
Introduction
Foam injection molding (FIM) is one of the most promising technologies owing to its ability to
produce low-density parts with high geometrical accuracy and stiffness-to-weight ratio at fast
production cycles [i]. In this technology, a gas-charged melt is being injected into a confined cavity.In low-pressure FIM, i.e. short shot injection, foaming occurs due to the pressure drop ov...

Hierarchical mesoporous Zn-Ni-Co-S microspheres grown on reduced graphene oxide/nickel foam (rGO/NF) for asymmetric supercapacitors
Abstract: In this work, hierarchical mesoporous Zn-Ni-Co-S-rGO/NF microspheres have been prepared by hydrothermal, sulfurization, and subsequent calcination process. The effect of different sulfurization time on the morphology and capacitance of composites was tested. The high electrochemical performance of (Zn-Ni-Co-S-rGO/NF) composite was obtained when the sulfurization time was...

Density Effect on Flame Retardancy, Thermal Degradation, and Combustibility of Rigid Polyurethane Foam Modified by Expandable Graphite or Ammonium Polyphosphate
The current study aims at comparatively investigating the effect of apparent density on flame retardancy, thermal degradation and combustion behaviors of rigid polyurethane foam (RPUF), RPUF/ expandable graphite (EG) and RPUF/ ammonium polyphosphate (APP). A series of RPUF, RPUF/EG and RPUF/APP samples with different apparent densities (30, 60 and 90 kg/m) were prepared. The flame retardancy, ther...

Preparation, characterization and thermal degradation behavior of rigid polyurethane foam using a malic acid based polyols
A series of multi-functionality polyester polyols (MAP) were synthesized successfully by using a renewable resource of malic acid and 1,6-hexanediol via esterification. The chemical structure of MAP was characterized by proton nuclear magnetic resonance (1H NMR), Fourier-transform infrared (FTIR), gel permeation chromatography (GPC) as well as acid and hydroxyl values. Then it was used to prepar...

Highly selective and sensitive long fluorescence lifetime polyurethane foam sensor based on Tb-complex as chromophore for the detection of H2PO4? in water
Developing novel rare-earth complexes to rapidly and reliably sensing anions in pure water is highly challenging. Here, a series of long fluorescence lifetime polyurethane foam bonded Tb(BAA)3 chromophore porous material (Tb-PUFs) have been designed and synthesized via a simple one-step co-polycondensation reaction as an efficient fluorescent sensor for H2PO4? in pure water. All Tb-PUFs exhibited ...
