Mineral fibers and whiskers exhibiting reduced mammalian cell toxicity, and method for their preparation

摘要

An abatement of the cytotoxicity to cells caused by mineral fibers/whiskers through the surface treatment of the fibers/whiskers with a material that changes the surface structure which eradicate charge and confer hydrophobicity. By pretreating the fibers/whiskers with such materials, an industrial hygiene problem occurring in the fabrication and handling of mineral fibers/whiskers is significantly reduced. Studies were conducted on mouse embryo cells and fetal lung cells, with essentially complete abatement of cytotoxicity when the mineral fibers/whiskers are treated with a silicone.
