Special characteristics of wrinkles such as a scattering source and a high surface area are finding use in high-tech applications. UV-crosslinkable prepolymers are occasionally used for fabricating wrinkled films. Wavelength of the wrinkles formed from the prepolymers is several tens and hundreds of micrometers. Here, a UV-crosslinkable liquid prepolymer was synthesized to spontaneously form wrinkle structures in the order of several micrometers. Double layers with a very thin hard skin and a soft and contractible foundation were formed at the same time, by ensuring that all the absorbance wavelengths of the photoinitiator were shorter than the min. wavelength at which the prepolymer is transparent. The rate of photo-crosslinking reaction, Rp, is also found to affect the thickness of the skin and foundation layers at the early UV-curing stage. The first-order apparent rate constant, kapp, is between ≈0.20 and ≈0.69 s-1 for the wrinkle formation. This wrinkle structures can be simply modulated by changing Rp. In the experiment, the researchers used many compounds, for example, ((Oxybis(ethane-2,1-diyl))bis(oxy))bis(ethane-2,1-diyl) bis(2-methylacrylate) (cas: 109-17-1Synthetic Route of C16H26O7).
((Oxybis(ethane-2,1-diyl))bis(oxy))bis(ethane-2,1-diyl) bis(2-methylacrylate) (cas: 109-17-1) belongs to alcohols. Similar to water, an alcohol can be pictured as having an sp3 hybridized tetrahedral oxygen atom with nonbonding pairs of electrons occupying two of the four sp3 hybrid orbitals. A multistep synthesis may use Grignard-like reactions to form an alcohol with the desired carbon structure, followed by reactions to convert the hydroxyl group of the alcohol to the desired functionality.Synthetic Route of C16H26O7
