The SEM studies shows that P[NR/HAF-Dy(OH)_3] vulcanizate shows superior mechanical properties that depend primarily on the absence of free carbon black,the fine dispersion of carbon black in the rubber matrix and better polymer-filler interaction.

• SEM分析表明,HAF-Dy(OH)3以团粒形态存在于NR基体中,团粒表面覆盖一层NR膜,团粒与NR构成的界面模糊,说明HAF-Dy(OH)3与NR基体结合紧密,这是P[NR/HAF-Dy(OH)3]具有较好物理机械性能的主要原因。
