New Polyenes Study Findings Recently Were Reported by Researchers at Department of Materials Science & Engineering

May 30, 2014



By a News Reporter-Staff News Editor at Science Letter -- Current study results on Polyenes have been published. According to news originating from Beijing, People's Republic of China, by NewsRx correspondents, research stated, "A novel interpenetrating structural ultrafine polypropylene-silica nanocomposite particles were synthesized by a modified sol-gel approach in the presence of the melt polypropylene emulsion. A series of samples with different polypropylene content was prepared to investigate the unique characteristics of this original nanocomposite."

Our news journalists obtained a quote from the research from the Department of Materials Science & Engineering, "The thermal gravimetric analysis and differential scanning calorimetry results showed that the nanocomposites had the interpenetrating structure and good thermal stability, and the crystallization behavior of polypropylene was confined by the silica matrix. The interpenetrating structure of nanocomposites was also suggested by the nitrogen adsorption-desorption measurement results. The scanning electronic microscope and transmission electron microscopy images indicated that the nanocomposites had irregular particle morphology. The nanoparticle tracking analysis results show that the mean size of the nanocomposites was around 160 nm."

According to the news editors, the research concluded: "According to the results obtained from different measurements, a reasonable formation mechanism was proposed."
