Polymer micelles have been extensively developed for medical applications. For instance, micelles with a (polyethylene glycol (PEG) outer shell are widely used due to their stability and ability to prevent non-specific adsorption to proteins and cells. Compared to PEG, Poly(2-isopropyl-2-oxazolines) (PIPOX) offers similar properties but exhibits a higher equilibrium spreading pressure than albumin. Based on this characteristic, amphiphilic block copolymer PS-PIPOX micelles may serve as more effective synthetic surfactants. We investigate and compare the surface tension-reducing capabilities of PEG and PIPOX at identical concentrations in water. Subsequently, light scattering methods were used to measure the cloud points of water solutions of both samples at the same concentration over a range of temperatures. Future work includes further comparison between the performances of PS-PEG micelles and PS-PIPOX micelles at albumin-saturated aqueous surface.
