The testing methods for evaluating the optoelectronic performance of bismuth trioxide doped radiation protection clothing mainly include the following:

1. Scanning Electron Microscopy (SEM)

Used to examine the morphological characteristics of the material, including particle size, distribution, and surface morphology.

2. Energy Dispersive X-ray Spectroscopy (EDX)

Used for analyzing the chemical composition and elemental composition of the material.

3. Fourier Transform Infrared Spectroscopy (FT-IR)
Used to study the infrared absorption spectra of the material to understand its chemical structure and functional groups.


4. Commercial Computerized Tomography (CT) device

Used to study the X-ray characteristics of coated PES spun-bond materials, including linear attenuation coefficient, half-value layer (HVL), and tenth-value layer (TVL) thickness.

5. Electrostatic Meter

Used to measure X-ray attenuation of samples to evaluate their shielding performance.

6. Taguchi Method

Used for optimizing material formulation design, including cement content, water-cement ratio, bismuth trioxide ratio, and sand ratio.

7. MCNP5 (Monte Carlo N-Particle 5) simulation

Used for simulating and calculating the radiation shielding performance of materials, comparing and validating results with experimental data.
The above 7 testing methods comprehensively evaluate the optoelectronic performance of bismuth trioxide doped radiation protection clothing, including its morphological characteristics, chemical composition, X-ray attenuation, and shielding performance.
