Injection Molding of Superhydrophobic Submicrometer Surface Topography on Macroscopically Curved Objects: Experimental and Simulation Studies

Abstract: Micro-and nanoscale surface topographies that give rise to superhydrophobic surfaces have been achieved mostly on 2-dimensional planar objects. Increasing interests in superhydrophobic surfaces on consumer products, optics, and biomedical devices demand topographic patterning on freeform nonplanar surfaces via a high throughput manufacturing process such as injection molding. However, successes in highresolution (submicrometer) injection molding have been limited to flat and planar objects. A challenge associa… Show more

“…Holzer et al [107] fabricated grooves of 18 nm in width on polymer. Lee et al [108] combined Moldflow and pressure-driven deformation modeling to optimize the process of micro-injection molding and produced 300 nm grating texture. Stormonth-Darling et al [109] produced a pillar nanostructure with an ultra-high aspect ratio of up to 20:1.…”

“…Wang et al ( Wang et al, 2018 ) fabricated honeycomb-like micro surface arrays with different contact angles by means of micro-injection ( Figure 6A ). Li et al ( Lee et al, 2019 ) successfully achieved the preparation of curved parts with sub-micron surface morphology through micro-injection and nano-imprinting ( Figure 6B ). Zanchetta et al ( Zanchetta et al, 2015 ) fabricated devices with different microscopic features and studied the proliferation and differentiation of cells under different microscopic features ( Figure 6C ).…”

“…Although some researchers have shared their definitions of micro-molded products, which will be Polymers 2021, 13, 2877 2 of 41 discussed later in this paper [1,[4][5][6][7][8], the size of the micro-molded parts is expected to exceed their definitions due to the continuous development of MIM. In fact, micro-molded parts have been gradually extending to sub-micron [9][10][11] or even nano-scale [12][13][14].…”
