Polydimethylsiloxane-Modified Polyurethane as Antifouling Coatings

Researchers from China investigated the effects of polydimethylsiloxane (PDMS) modification of polyurethanes on antifouling properties of the fouling release coatings. Various analytical techniques such as confocal laser scanning microscopy (CLSM), atomic force microscopy (AFM), Fourier transform infrared spectroscopy (FTIR), differential scanning calorimetry (DSC), thermogravimetric analysis (TGA) and X-ray diffraction (XRD).were used for characterization. It was shown that the presence of PDMS increased the degree of microphase separation, and enhanced the water resistance of the coatings. The presence of PDMS benefited the removal of weakly attached organisms and PDMS-modified polyurethane showed the antifouling activity.
