摘要

随着个体辐射防护和柔性防护装备的发展，伽马射线屏蔽材料对轻质化、柔性化和无铅化提出了更高要求. 为提高柔性聚合物基复合材料的

射线屏蔽性能，以聚丙烯腈(PAN)为基体，制备了Bi

及不同La掺杂的复合纳米纤维膜，并结合微观表征及性能测试，系统研究了La掺杂对复合纤维膜微观结构、局域电子结构、力学性能及

射线屏蔽性能的影响. 实验结果表明，La掺杂能够显著调控Bi

的结晶行为和纤维表面无机相的生长状态，且掺杂量与复合纳米纤维膜性能之间并非简单的线性关系，适量La掺杂有利于改善无机相在纤维表面的分布均匀性并优化复合膜结构，而过量掺杂会导致含镧杂相生成及局部富集，其中10 wt% La掺杂样品表现出最佳的综合性能，在3种辐照条件下的质量衰减系数分别达到4.426、1.491和1.315 cm

·g

-1

，较未掺杂La的样品分别提高约51.6%、77.7%和151.4%. 该研究为轻质、柔性、无铅

射线屏蔽纤维材料的结构设计与性能优化提供了参考.

Abstract

With the development of personal radiation protection and flexible protective equipment

gamma-ray shielding materials face higher requirements for lightweight

flexibility

and lead-free characteristics. To improve the gamma-ray shielding performance of flexible polymer-based composites

we prepared Bi

and Bi

/PAN composite nanofibrous membranes with different La doping contents using polyacrylonitrile (PAN) as the matrix. Combined with microstructural characterization and performance testing

the effects of La doping on the microstructure

local electronic structure

mechanical properties

and gamma-ray shielding performance of the composite nanofibrous membranes were systematically investigate. The results showed that La doping significantly regulates the crystallization behavior of Bi

and the growth state of the inorganic phase on the fiber surface

and the relationship between La doping content and the properties of the composite nanofibrous membranes was not simply linear. Appropriate La doping improved the distribution uniformity of the inorganic phase on the fiber surface and optimizes the membrane structure

whe

reas excessive doping caused the formation of La-containing impurity phases and local aggregation. The 10 wt% La-doped sample exhibited the best overall performance

with mass attenuation coefficients of 4.426

1.491

and 1.315 cm

·g

-1

under three irradiation conditions

which were approximately 51.6%

77.7%

and 151.4% higher than those of the undoped samples

respectively. This study provides a reference for the structural design and performance optimization of lightweight

flexible

and lead-free gamma-ray shielding fibrous materials.
