CA 2139357

A method of preventing charged particles from passing through holes in a barrier material which involves surface treating a barrier material with an ionic surfactant to impart a charge to the barrier material. In a preferred embodiment, prophylactics such as condoms and surgical gloves can be treated with an anionic surfactant. Tests have confirmed that such surface treated ar- ticles can repel virus particles such as human immunodeficiency (HIV) virus, hepatitis B virus and herpes simplex virus (HSV). Ionic surfactant treated articles include prophylactics such as condoms and diaphragms, gloves, including surgical gloves, surgi- cal masks, respiratory masks and filters, filters, including membrane, and wound dressings, including bandages.
