Patent ID: 7807212

Claim:
A plasma method for depositing a titanium oxide (TiO x ) biomedical material onto a hydrophilic polymer film, comprising steps of: (a) obtaining said hydrophilic polymer film coated with an organic titanium (Ti) solution formed through a sol-gel method, said sol-gel method comprising steps of: (a1) dissolving a precursor of Ti Isopropoxide (TIP) into an organic solution; (a2) obtaining an organic Ti solution from said organic solution by using ultrasonic waves; and (a3) spin-coating a layer of said organic Ti solution on a surface of said hydrophilic polymer film; and (b) processing a plasma activation treatment to said hydrophilic polymer film coated with said organic Ti solution under a vacuum pressure with oxygen (O 2 ) having a pressure to obtain a TiOx film onto said hydrophilic polymer film.
