Novel Composite Materials of Polymers with Surfactants and Liquid Crystals

提出了新型复合聚合物材料的制备和研究。 The particular class of structures are polymer thin films via surfactant templates which have been recently developed in the PI's laboratory. This project will ascertain the scope and uniqueness of the films, and will further emphasize the characterization of films formed by this new method. Generality of the thin film process will be explored for various hydrophilic and hydrophobic substrate, polymers of different type and molecular structure, and various types of surfactant. Characterization will include molecular weight determination by gel permeation chromatography, test of film uniformity and reproducibility by several physical methods, and examination of the films structures on the substrate by various microscopic techniques. 还提出了一种不寻常类型的新型表面活性剂的合成，即碳氢化合物/氟碳杂化表面活性剂。 杂化表面活性剂将与薄膜技术一起使用，以形成图案化的聚合物薄膜。

The fabrication and investigation of novel composite polymer materials is proposed.

Generality of the thin film process will be explored for various hydrophilic and hydrophobic substrate, polymers of different type and molecular structure, and various types of surfactant. Characterization will include molecular weight determination by gel permeation chromatography, test of film uniformity and reproducibility by several physical methods, and examination of the films structures on the substrate by various microscopic techniques. The synthesis of an unusual type of new surfactant, namely hydrocarbon/fluorocarbon hybrid surfactant, is also proposed. The hybrid surfactant will be used with the thin film techniques in order to form patterned polymeric films.
