The hydrated surface of a hydrogel-coated latex urinary catheter has been examined using low temperature SEM, and its appearance compared with those of some other catheter surfaces. The effect of the coating is to smooth over most of the ripples and fissures of the underlying latex. On hydration the hydrogel surface becomes even smoother, with shallower furrows. The surface topography compares favourably with that of 100% silicone, which has a uniformly rippled yet smooth appearance.
已使用低温扫描电子显微镜检查了水凝胶涂层乳胶导尿管的水合表面，并将其外观与其他一些导管表面的外观进行了比较。涂层的作用是抚平底层乳胶的大部分波纹和裂缝。水合后，水凝胶表面变得更加光滑，沟槽更浅。其表面形貌与100%硅胶的表面形貌相比具有优势，100%硅胶具有均匀的波纹但表面光滑。
