We are seeking to deposit a thin film to the inside surface of a hollow fiber membrane for a hollow fiber field flow fractionation channel. The native hollow fiber characteristics are: Outside diameter: 1.0mm, Inside Diameter 0.5mm, NWCO 10kDa. The thin film characteristics we seek are: NWCO 100Da, more homogeneous pore structure, reduction in roughness, low protein binding. Interfacial polymerization is a candidate method for depositing this thin film. Polyethylene glycol is a candidate polymer due to its low protein binding characteristics. I have attached a paper that describes interfacial polymerization of a hollow fiber. I have attached another paper that describe interfacial polymerization using polyethylene glycol. We are seeking the development of a thin film deposition method that can be performed by our mechanical engineers. As such, it needs to be a set of steps that an engineer without chemistry training can reasonably perform.
