对自行设计的高速混床“多支管布水+多孔帽”布水结构(模型1)和传统“一次挡板+水帽”布水结构(模型2)树脂颗粒表层扰动进行了研究。通过对比模型1高速混床试验和模拟压差值证明了模拟方法的有效性。在此基础上,对2种布水结构在流速为140 m/h时的出水流速分布进行模拟。结果表明,模型1出水流速分布更为均匀,且最大流速明显小于模型2。针对树脂颗粒之间互相作用力复杂、难以通过仿真模拟树脂颗粒表层真实搅动状态的问题,采用试验法观测树脂颗粒表层搅动状态。结果表明,模型1树脂颗粒表层发生搅动临界流速位于80~100 ...

采用蒙特卡罗(Monte Carlo)结合退火技术研究了线性梯度高分子与纳米颗粒共混体系的相分离行为.模拟研究发现其相分离不但与梯度高分子的分布函数f(t)有关,还与链长、相互作用能和纳米颗粒浓度相关.随着参量的改变发现了无序相与层状相(L)或穿孔层状相(P)以及无序相与球状相(S)相变,此外,当在特定的单体A浓度时同时还出现了共混相,同时纳米颗粒随机分布在单体A区域内.

ABSTRACT Metal oxide‐based catalysts for oxygen reduction reaction (ORR) have drawn great attention in recent years. However, it remains technically challenging for the precise regulation of the overall performance due to the trade‐off effect among the activity, selectivity, and stability of electrocatalysts. Herein, a balancing strategy to control the

Filling Uniformity of AgNPs in EMI Shielding Patch Regulated by Surface Morphology
ABSTRACT Silver nanoparticles (AgNPs) are extensively employed for electromagnetic interference (EMI) shielding owing to their remarkable conductivity, and are commonly incorporated into polymer matrices. Therefore, the uniformity of the AgNP distribution within the polymer matrix is a crucial factor that affects the EMI shielding performance.
