1) Heat Insulation: Single-foaming structure can reduce the loss of heat between air convections, suitable for making heat preservationPipes and boards. Good anti-dew capability, suitable for humid environments like refrigerators,Air-conditioners, ice houses, etc.2) Cushion...
Polymers are a vital part of everyday life. Their chemical universe is so large that it presents unprecedented opportunities as well as significant challenges to identify suitable application-specific candidates. We present a complete end-to-end machine-driven polymer informatics pipeline that can searc...
They performed solvothermal liquefaction of microorganisms in polyethylene glycol and glycerol in the presence of sulfuric acid as a catalyst. The authors pointed out that algae are a promising raw material for liquefaction because, unlike most types of biomass, they do not contain lignin, which ...
Polyethylene (C2H4)n was compressed to pressures between 10 and 30 GPa in a diamond anvil cell (DAC) and laser heated above 2500 K for approximately one second. This resulted in the chemical decomposition of the polymer into carbon and hydrocar
As for bio-based FDCA, it can be used for the production of polyethylene furanoate (PEF), and thus, replace terephthalic acid (TA), a petroleum-based monomer mainly used for the production of PET. According to Avantium, 100% bio-based PEF is a next-generation polyester offering superior ...
[23] used mapping Raman Spectroscopy to analyze a polypropylene/polyethylene copolymer blended with small amounts of ethylene-propylene rubber appearing as micrometer domains that, after Ar-plasma treatment, increased in size because of their resistance to damage due to crosslinking. Dufour et al. ...

However, despite the numerous advantages associated with the use of natural fibers, a significant limitation lies in their hydrophilic nature due to the presence of strongly polarized hydroxyl groups in their lignocellulosic structure. This characteristic renders vegetable fibers incompatible with hydrophobic...
