By measuring the equilibrium and cyclic π～A isotherms and dynamic elasticities of octadecylamine monolayers on the subphases of water and CdCl 2 solution, it is showed that Cd 2+ added into the subphase can enhance the condensability of liquid-like monolayer but decrease that of the solid-like monolayer.

The research indicated that, the structure inside the pure C8TES SAM was indeed loose and unassembled completely, the molecule density inside the SAM was very low, which would result in an ultra-low surface contact angle, only 20～21°, on the C8TES SAM surface.

我们的研究表明，由于C8TES分子头部三个乙氧基形成的空间(来源：b5e5ABe3C论文网www.abclunwen.com)位阻的影响，C8TESSAM的内部处于一种不完全组装的松散状态，所形成的自组装单分子膜内分子密度偏低，造成C8TES SAM的表面接触角偏低，只有20～21°。

In this research, mixed SAM of HS-(CH2)15-CH3 and HS-(CH2)15-COOH was immobilized on gold substrate through chemical bond, and PEG and PMB were in sequence linked to the –COOH terminal groups on the SAM sureface by EDC/NHS amide coupling. The PMB immobilized surface was applied to study its specific and nonspecific interactions with LPS by ellipsometry and by SPR spectroscopy. The modified surface is characterized by FTIR, XPS, ellipsometry and contact angle measurements.
