一般描述

十八烷基膦酸（OPA）可用作自组装单层膜，其可形成与不同金属氧化物的表面原子牢固结合的表面活性剂。与主要使用的硅烷相比，它具有疏水性并可覆盖更大的表面积。

应用

白铜（CuNi）上的防腐涂层可以通过浸涂法在OPA的保护膜上形成。OPA可用于制备氧化铟（In2O3）纳米线晶体管，并可能用于快速转换和低噪音纳米电子器件的增长。它可以在铜网上形成超疏水层，因此可用于自清洁和油/水分离应用。

Flexible Organic Transistors for Biomedical Applications

There is widespread demand for thin, lightweight, and flexible electronic devices such as displays, sensors, actuators, and radio-frequency identification tags (RFIDs). Flexibility is necessary for scalability, portability, and mechanical robustness.

Micro and Nanometer Scale Photopatterning of Self-Assembled Monolayers

Self-assembled monolayers (SAMs) have attracted enormous interest for a wide variety of applications in micro- and nano-technology. In this article, we compare the benefits of three different classes of SAM systems (alkylthiolates on gold).
