论文摘要
我们研究了与直接的小角度中子散射测量值的同型聚丙烯基质中碳同素纳米纤维的聚集。借助ATSAS软件,我们分析了数据并确定了散射角度范围内的大部分同骨聚丙烯中纳米填料聚集的分形形状,尺寸和尺寸。我们估计了不同浓度的不同类型的碳纳米燃料的体积分布和聚合:纳米仪,石墨烯纳米片(GNP),单壁碳纳米管(SWCNT),多壁碳纳米管(MWCNT),MWCNT),binary Fillers Mwcnt/binary Fillers mwcnt/gnp and gnp and fullereSes。我们重建了所有纳米填料的纳米级骨料的形状,发现系统是多分散的。 Nanofillers将IPP的体积与分形骨料相关联,其大小超过了纳米列的原始尺寸多次。
We study the aggregation of carbon allotrope nanofillers in the matrix of isotactic polypropylene with direct small-angle neutron scattering measurements. With the ATSAS software, we analyzed the data and determined the fractal shape, dimension, and sizes of nanofiller aggregation in the bulk of isotactic polypropylene over the range of the scattering angles. We estimated the volume distributions and aggregation of different types of carbon nanofillers at different concentrations: nanographite, graphene nanoplatelets (GNP), single-walled carbon nanotubes (SWCNT), multi-wall carbon nanotubes (MWCNT), binary fillers MWCNT/GNP and fullerenes. We reconstructed the shape of nanoscale aggregates of all nanofillers and found that the systems are polydisperse; nanofillers associate in the volume of iPP as fractal dense aggregates with rugged surface, their sizes exceeding original dimensions of nanofillers several times.
