CuSO_4 Micro-crystal Lattice Produced by microcontact printing

Chemical Research in Chinese Universities 2002年第2期18卷 221-222页

An elastic stamp was produced by molding poly(dimethylsiloxane)(PDMS) against a master with micro\|patterns on the surface. Then a procedure named microcontact printing was carried out on the glass substrate with the ink of an octadecylsiloxane(OTS) solution. The OTS reacted with the glass and formed a self\|assembly monolayer, and the process produced hydrophobic micro\|patterns on hydrophilic substrate. Owing to a simple hydrophobic interaction between the CuSO\-4 solution and the monolayer, a regular CuSO\-4 micro\|crystal lattice could be produced.

Wafer scale direct-write of Ge and Si nanostructures with conducting stamps and a modified mask aligner

The broad availability of high throughput nanostructure fabrication is essential for advancement in nanoscale science. Large-scale manufacturing developed by the semiconductor industry is often too resource-intensive for medium scale laboratory prototyping. We demonstrate the inexpensive wafer scale direct- write of Ge and Si nanostructures with a 4-inch mask aligner retrofitted with a conducting microstructured stamp. A bias applied between the stamp and an underlying silicon substrate results in the reaction of diphenylgermane and diphenylsilane precursors at the stamp--substrate interface to yield the direct- write of Ge and Si nanostructures in determined locations. With the increasing number of outdated mask aligners available from the semiconductor industry and an extensive library of liquid precursors, this strategy provides facile, inexpensive, wafer scale semiconductor direct-write for applications such as electronics, photonics, and photovoltaics.

Durable,high conductivity,superhydrophobicity bamboo timber surface for nanoimprint stamps

Progress in Natural Science:Materials International 2017年第6期27卷 669-673页

作者： Wenhui Bao Daxin Liang Ming Zhang Yue Jiao Lijuan Wang Liping Cai Jian Li Research Center of Wood Bionic Intelligence Northeast Forestry University College of Materials Science and Engineering Northeast Forestry University Engineering College University of North Texas

Superhydrophobic bamboo timber was fabricated by magnetron sputtering and nanoimprint stamps. Conductive copper film was deposited on the surface of bamboo timber, followed by transferring lotus leaf structure pattern to the Cu-bamboo timber surface. Modified by stearic acid, the as-prepared surface with lotus leaf structure showed superhydrophobic property with the water contact angle of 152°, and the sliding angle was only 5°. The coating showed excellent mechanical resistance, environmental stability and high conductivity. It was expected that this work could promote the applications of superhydrophobic and conductive bamboo products.
