摘要： Fluoropolyether compounds that can be used as a lubricant, such as for magnetic recording media. The compounds have a terminal group that includes a phenol or benzene. The fluoropolyether compounds reduce the head to media distance while keeping comparable reliability in a hard disk drive compared to current industrial widely used fluoropolyether based lubricants.
