1. Wearing apparel for shielding a wearer from electromagnetic or radio frequency or microwave radiation produced by electronic equipment;
- wherein the apparel comprises a shell of flexible material containing a flexible insert having a copper-based coating applied thereon in an amount sufficient to shield the wearer from the electromagnetic, radio frequency or microwave radiation;
the insert being made by the following steps;
(a) preparing electroless plated copper, which comprises the following steps in the order named;
(i) adding to an alcohol reaction bath copper particles to a concentration of about 25% to about 35% w/v relative to the alcohol component;
(ii) adding distilled water in an amount of about 200.00% to about 300.00% w/v relative to the alcohol component;
(iii) adding a non-ionic surfactant to a concentration of about 0.0009% to 0.06% w/v relative to the alcohol component;
(iv) adding a dilute acid to a concentration of about 0.5% to about 2.0% w/v relative to the alcohol component;
(v) adding an anionic surfactant to a concentration of about 0.050% to about 0.100% w/v relative to the alcohol component;
(vi) adding a plating metal to a concentration of about 1.0% to about 4.5% w/v relative to the alcohol component to produce plate copper particles;
(vii) collecting the plated copper particles by filtration;
(Viii) washing the treated copper with water;
(ix) washing the plated copper particles with alcohol;
(x) adding the plated copper particles to a solvent base resin to produce a plated copper/resin mixture having a plated copper particle to resin ratio of about 0.5;
1 to about 8;
1, and(b) applying the plated copper/resin mixture to a substrate.

Abstract
EMR/RFR/MWR (Electromagnetic Interference/Radio Frequency Interference/Microwaves) body shield composition comprises a copper base having a coating applied thereon by electroless deposition which may be applied directly to a fabric or other substrate which is inserted into wearing apparel. Preparation of the copper-based coating is also disclosed.
