Abstract

Abstract: Crosslinked colloidal monolayers are promising as templates, lithographic masks, filtration membranes, or membranes for controlled release rates in drug delivery. We demonstrate assembly of monodisperse micron-sized polystyrene (PS) beads at an air/water interface, which are transformed into crystalline monolayers using addition of surface-active agents. Vapor annealing methods with solvents (toluene and xylene) and crosslinking agents (divinylbenzene) were investigated regarding their ability to crosslink these floating monolayers directly at the interface, generating crosslinked membranes with crystal size up to 44 cm2, domain size up to 1.9 mm2, and nano-sized pores (100-300 nm). The demonstrated fabrication method emphasizes short fabrication time using a simple setup.

漂浮胶体单层的交联。
摘要:交联胶体单层膜是一种很有前途的模板、光刻掩膜、过滤膜或药物释放控制膜。我们展示了在空气/水界面上组装单分散微米级聚苯乙烯(PS)珠,并通过添加表面活性剂将其转化为结晶单层。研究了溶剂(甲苯和二甲苯)和交联剂(二乙烯基苯)的蒸汽退火方法在界面处直接交联这些漂浮单层的能力,生成了晶体尺寸达44 cm2、畴尺寸达1.9 mm2和纳米孔径(100-300 nm)的交联膜。所演示的制造方法强调使用简单的设置缩短制造时间。图形化的简介:

期刊介绍: "Monatshefte für Chemie/Chemical Monthly" was originally conceived as an Austrian journal of chemistry. It has evolved into an international journal covering all branches of chemistry. Featuring the most recent advances in research in analytical chemistry, biochemistry, inorganic, medicinal, organic, physical, structural, and theoretical chemistry, Chemical Monthly publishes refereed original papers and a section entitled "Short Communications". Reviews, symposia in print, and issues devoted to special fields will also be considered.
