Abstract: A mobile phone proofed against water, dust, and physical shocks (tri-proofed) has a structure comprising a first casing, a second casing, and a third casing. The first casing is provided with protrusions, and the third casing is provided with convex blocks. The second casing is provided with a first groove for a protrusion, and is provided with a second groove for a convex block. The protrusions and the convex blocks are both interference fits in the grooves. Moreover, the second casing also includes cosmetic surfaces. The first casing and the third casing have outer surfaces and each cosmetic surface protrudes out of the outer surfaces. The cosmetic surfaces are in first contact when the mobile phone is dropped. Waterproofing, dustproofing, and shockproofing are simultaneously achieved with the single second casing structure.

Abstract: A method of modifying substrate surface includes: performing an O2 plasma treatment on a substrate including polydimethylsiloxane (PDMS); coating hydrophilic UV curing coating uniformly on the substrate; disposing the substrate into an oxygen-free environment; and exposing to an UV light to cure the hydrophilic UV curing coating. The method of modifying substrate surface may greatly enhance the hydrophilicity and the stability of the PDMS substrate.

The link members form an array of geometric unit cells when the structure is expanded, and the height and the width of the structure when expanded are both greater than the height and the width of the structure when collapsed. In certain embodiments the structures have unit cells based upon triangles or bowtie shapes.
