“…The need for protection against neutron radiation is also urgent in space, where protection against cosmic radiation (high-energy heavy particles) [1] during travel and equipment operation 1254 (2023) 012100 IOP Publishing doi:10.1088/1755-1315/1254/1/012100 2 is important. The main task of neutron-absorbing materials is to cut off the neutron part of the spectrum during the collision with high-energy particles, which reduces the radiation load.…”

The nature and properties of neutron radiation impose specific requirements on the creation and operation of such materials. The presence of accompanying and induced radiation, weather conditions, as well as the peculiarities of the location of functional layers require a hierarchical approach to the development of such neutron-absorbing materials. It was shown that the conceptual scheme of creating Gd-containing protective materials consists in taking into account all factors of their operation. In particular, it is shown that the presence of neutron-absorbing components is a necessary but not sufficient condition for their successful application in environmental conditions. In this work, Gd-containing chitosan films were prepared as an example of the proposed conceptual scheme for the creation of environmentally friendly neutron-absorbing nanocomposites. The prepared Gd films were characterized and their neutron permeability was estimated. The approach presented in this work contributes to the development of sustainable and responsible production practices, supporting SDGs 9 and 12.

A novel methodology is introduced to asses the efficacy of cosmic radiation shielding through the fabrication of electrospun nanocomposite fiber mats reinforced with hexagonal boron nitride (h‐BN) and carbon nanotubes (CNTs). These mats were fabricated using various h‐BN particles synthesized with 1 M boric acid and four distinct 1 M nitrogen sources to produce polyethylene oxide (PEO) nanofibers via the electrospinning method at 15 kV, a 43.0 μL/min pumping rate, and a 20 cm distance with a maximum thickness of 10 μm. High neutron shielding capability nanocomposite fibers denoted BN‐F4 (spun with h‐BN [melamine]/CNT powders in a 5 wt% PEO solution) and BN‐F5 (spun with h‐BN [urea]/CNT powders in a 5 wt% PEO solution) were produced. By calculating the theoretical photon transmittance and evaluating the neutron shielding efficiency with an Am‐Be neutron source and a BF3 neutron detector, the cosmic radiation shielding capability of nanocomposite mats was discussed. BN‐F4 and BN‐F5 exhibited neutron shielding properties of 7.124% and 6.37% for 3.82 and 1.87 g/mL, respectively. This research establishes a new benchmark in the fabrication of flexible, ultrathin, and lightweight radiation shielding materials and enhances the practicality of nanocomposites reinforced with h‐BN and CNTs by incorporating synthesizing and characterizing steps.Highlights In the study, hexagonal boron nitride production was carried out with four different nitrogen sources and which one showed better structural and morphological properties was supported by analysis. Additionally, an optimization study of nanofibers by electrospinning by adding CNT and h‐BN particles with PEO polymer is included. It is thought that the production of h‐BN and nanofiber work as a radiation shielding feature for use in space studies will be innovative and contribute to the deficiency in the literature.
