The dispersions and particles sizes of the fg nanosheets in the nanocomposites greatly influenced the conduction of the nanocomposites , especially the percolation threshold 石墨纳米薄片在尼龙6中的分布状态以及尺寸大小对复合材料的电导,尤其是导电渗滤阈值具有相当大的影响。
At present , preparation of nylon 6 / montmorillonite nanocomposite is relatively mature , but there are few reports and articles about preparation of nylon 66 / montmorillonite nanocomposite 目前尼龙6蒙脱土纳米复合材料的制备已比较成熟,而尼龙66蒙脱土纳米复合材料的制备鲜有报道。
Isothermal and non - isothermal crystallization experiments conducted for the nanocomposite showed that addition of graphite nanosheets significantly changes the crystallization behaviors of the nylon 6 resin 复合材料体系的等温及非等温结晶实验显示,石墨纳米薄片的加入显著改变了尼龙6的结晶行为及结晶机理。
However , the critical exponent was found to be slightly higher than the universal one . for modeling the conduction behavior , the general effective media equation was demonstrated to be the most effective one 在所有方法中通用有效介质方程( generaleffectivemediaequation )对尼龙6石墨薄片纳米复合材料导电行为的模拟最为有效。
According to the different modifier , it is classified as follows : inorganic nanoparticle / nylon 6 in - situ composite , organic polymer / nylon 6 in - situ composite and carbon nanotube / nylon 6 in - situ composite 基于改性剂的不同,将其分为无机纳米粒子尼龙6原位复合材料、有机高分子聚合物尼龙6原位复合材料和碳纳米管尼龙6原位复合材料。
In this thesis study , graphite nanosheets were effectively prepared from natural graphite flake . fabrication of graphite nanosheets with nylon 6 via an in - situ polymerization approach led to the nylon 6 / foliated graphite nanocomposites 通过原位聚合复合技术,将石墨纳米薄片分散于尼龙6基体中,构造了尼龙6纳米石墨纳米导电复合材料。
On the condition of high speed and high load , the worn surface of pam 1 / nylon 6 composites nearly melt and comparatively uniform transfer on the surface of steel is formed , which accounts for the rather low wear mass loss 高速高载时,尼龙6和刚性较小的pam2 /尼龙6复合材料磨损表面处于粘流态,并在钢环表面形成了连续的转移膜,表现出较好的耐磨损性能。
At the same cooling rate , the crystallization rates of pam 1 / nylon 6 increase with the contents of pam1 ; while the crystallization rates of pam2 / nylon 6 attain maximum with 5 % contents of pam2 在同一降温速率时, pam1 /尼龙6复合材料随着pam1含量的增加, t _ p逐步向高温方向移动,结晶速率加快;在pam2 /尼龙6复合材料体系中,当含量为5左右时,出现最大结晶速率。
In this paper , three different kinds of polyazomethines ( pam ) / nylon 6 in situ polymerization composites were prepared using the process of monomer casting . their structures , thermal properties and also mechanical properties were analyzed 本文利用三种聚甲亚胺的单体与尼龙6单体通过原位聚合反应,制备了三种聚甲亚胺/尼龙6原位聚合复合材料,制备工艺采用浇铸法。
After 20 milling cycles , the particle size of pa6 can be reduced from original 3 - 4mm to around 1 m . some particles even reached nano scale ( 40 - 80nm ) after 30 milling cycles . pan - milling has great influence on polymer structure 经过20次碾磨循环,初始粒径为3 4mm的尼龙6粒子平均粒径可减少到3 m左右,经过30次碾磨循环,部分粒子粒径甚至可达纳米级( 40 80nm ) 。
