A Facile Process Combined with Electroless Deposition and Hydrophobic Treatment to Fabricate Self-cleaning Radiation Protection Suits for Pregnant Woman

Silver-printed terylene is presented to fabricate anti-electromagnetic radiation Maternity Dress (AMD) with superior shielding effectiveness, but the use of noble metal as electromagnetic interference shielding materials enhances cost of raw material and restricts its application. In this study, a facile process combined with electroless deposition and hydrophobic treatment to fabricate self-cleaning radiation protection cotton for AMD was established. The active groups on the plant fiber surface could absorb Sn 2+ and Pd 2+ through coordination effect, acting as catalytic center, which can catalyze the reduction of Ni 2+ in the plating solution. Ni particle deposited on the its surface with deposited amount of 32 %. The fabricated material exhibited an shielding effectiveness of 52.5 dB and it meet AMD criteria. Owing to the cooperation of the low surface energy and rough structure of precipitation, the Ni-plated cotton modified with (3-Mercaptopropyl) trimethoxysilane exhibited remarkable hydrophobicity with water contact angle up to 112.8° and excellent self-cleaning property.
