Patent ID: 8795718

Claim:
A hemostatic article consisting of: a) a fibrous substrate consisting of one or more fibers, said fibers being selected from the group consisting of lyocell fibers, rayon fibers, aramid fibers, acrylic fibers, polyester fibers, polyolefin fibers, poly(p-phenylene-2,6-benzobisoxazole) fibers, liquid crystal polymer fibers and combinations thereof; and b) a uniform film coating having a thickness of 5 nm to 100 nm on a surface of the fibrous substrate, said 5 nm to 100 nm uniform film coating consisting of a hemostatically effective, hydrophilic oxide, wherein the hemostatically effective, hydrophilic oxide coating consists of SiO 2 , a silicate, aluminosilicate, GeO 2 , silicogermanate, germanate, AlPO 4 , a metal or main group element aluminophosphate, Fe 2 O 3 , or a mixture thereof, and wherein the uniform film coating on the fibrous substrate is formed by chemical vapor deposition, plasma-enhanced chemical vapor deposition or atomic layer deposition.
