Nitrile gloves enhanced with nanofibers: Comparing integrated reinforcement vs. surface coating for superior radiation resistance in medical and nuclear applications.

This study compared the radiation resistance of nanofiber-reinforced woven (NFW) and surface-coated (SC) gloves to identify the optimal integration method for enhanced durability. Samples (n = 3 per condition) were subjected to electron beam irradiation at 10, 15, and 25kGy, then characterized using X-ray diffraction (XRD), Fourier Transform Infrared (FTIR) spectroscopy, scanning electron microscopy (SEM), energy-dispersive X-ray spectroscopy (EDS), and tensile testing. Results demonstrated significant differences (p < 0.001) between the two glove types: NFW gloves showed superior radiation resistance with crystallinity decreasing by only 35 % compared to 47 % in SC; nitrile functional groups were retained at 61 % versus 48 %; surface integrity was maintained with minimal cracking compared to 45 % coating delamination in SC; and mechanical properties showed better retention with NFW maintaining 68 % tensile strength versus 42 % in SC gloves at 25 kGy. The three-dimensional woven architecture effectively distributed radiation energy and protected the polymer matrix, while the surface coating approach proved vulnerable to direct radiation damage. Statistical analysis (ANOVA) confirmed significant performance differences at all dose levels. These findings establish nanofiber-reinforced woven integration as the preferred method for manufacturing radiation-resistant protective gloves, providing a solution for improved safety and reduced replacement costs in medical sterilization, nuclear facilities, and research laboratories.
