Chemistry of Materials 最近的综述很不错

       对于一个学物理出身的我,现在接触到的杂志五花八门。物理类的,化学类的,材料类的,等等。从4年前开始决定学材料物理到现在,接触的化学知识很多。如今,基本上的材料合成手段都是低温湿化学方法和CVD了。个人的感觉,化学也是一门很有趣的学科。这几年来,时不时都会从中找到灵感,并乐意去思考它。但是,如今,单纯的化学合成纳米材料已经一去不复返了。很多时候,让人觉得做纳米材料就是投机取巧。所以,我们已经向性质和应用转移。我自己07年来也一直都把主要精力放在性质和应用方面了。然而,材料的合成是一切应用的根本。我们必须首先接触化学,首先合成材料。从这点上,化学类的很多优秀的杂志都是不错的指导工具。我一直坚持关注它们。从中获得了很多知识。

      最近CM“Templated Materials”专辑有很多关于模版合成材料的综述。下了不少,呵呵。有时间好好啃。这里挑一片贴出来给大家看看。我常常想,他们做化学的很多都比较注重方法论和化学反应的动力学过程。我们可以借鉴他们的方法,首先做出好的材料,再作我们的本行:研究物理化学性质。这样不是很好?!

Morphological Control in Colloidal Crystal Templating of Inverse Opals, Hierarchical Structures, and Shaped Particles

Abstract:Inverse opals or three-dimensionally ordered macroporous (3DOM) materials, prepared by colloidal crystal templating (CCT) methods, possess distinctive structural features that are important for the design of photonic crystals, sensors, power sources, catalysts, and various other applications. In the past decade, vast progress has been made in shaping these materials at various length scales. It is now possible to prepare 3DOM materials in a variety of simple and complex compositions, in which pore sizes, pore shapes, and skeletal geometries can be adjusted statically and sometimes even dynamically to alter the physical properties of the material. Hierarchical pore structures can be achieved by combining CCT with additional templating techniques. Furthermore, shaped porous nanoparticles may be synthesized using CCT methods. This review will highlight recent advances in controlling both the internal structure of inverse opals and their external morphology, enhancing compositional complexity, endowing these solids with functionality, and incorporating them in integrated functional systems.
