研究目的
Studying luminescent properties of nanocomposites based on isotactic polypropylene and zirconium dioxide nanoparticles.
研究成果
The study concludes that polypropylene matrix acts as a chemically stable preservative for nanoparticles, preserving their spectral peculiarities. Strong interphase interactions between the PP matrix and ZrO2 nanoparticles alter the luminescent properties of the nanocomposites.
研究不足
The study is limited to the luminescent properties of nanocomposites based on isotactic polypropylene and zirconium dioxide nanoparticles, with specific focus on the effects of nanoparticle size and cooling rate on the properties of the nanocomposites.
1：Experimental Design and Method Selection:
The study involved the synthesis of nanocomposites by introducing ZrO2 nanoparticles into a polymeric solution of isotactic polypropylene in toluene, followed by drying and hot pressing.
2：Sample Selection and Data Sources:
Isotactic polypropylene powder with grain size
3：5-0 μm and ZrO2 nanoparticles stabilized by 3% of yttrium oxide were used. List of Experimental Equipment and Materials:
