说明

General description

对苯二甲酰氯是一种源自对苯二甲酸的高反应性酰氯。它在聚合物合成中用作交联剂。对苯二甲酰氯与双官能团α,ω-二氨基聚苯乙烯发生缩合反应，沿着聚合物主链生成含有酰胺键的扩链聚苯乙烯。它与牛血清白蛋白发生界面反应，形成交联薄膜。

Application

对苯二甲酰氯通过环状取代双（4-羟基苯基）对苯二甲酸酯的二氰酸酯化合物进行热环三聚反应，以用于合成液晶热固性化合物。

Molecular Layer Deposition of Polymers

Atomic layer deposition meets various needs including semiconductor device miniaturization and nanoparticle coating.

有机和有机无机杂化聚合物的分子层沉积

近十年来出现了原子层沉积（ALD）技术以满足各种需求，包括半导体器件小型化、多孔结构上的保形沉积和纳米颗粒涂层。ALD基于两个相继的自限性表面反应。

Fabrication of biomaterials via controlled protein bubble generation and manipulation.

Zeynep Ekemen et al.

Biomacromolecules, 12(12), 4291-4300 (2011-11-03)

In this work, we utilize a recently developed microbubbling process to generate controlled protein (bovine serum albumin, BSA) coated bubbles and then manipulate these to fabricate a variety of structures suitable for several generic biomedical applications, tissue engineering, and biosensor

Strong graphene oxide nanocomposites from aqueous hybrid liquid crystals.

Maruti Hegde et al.

Nature communications, 11(1), 830-830 (2020-02-13)

Combining polymers with small amounts of stiff carbon-based nanofillers such as graphene or graphene oxide is expected to yield low-density nanocomposites with exceptional mechanical properties. However, such nanocomposites have remained elusive because of incompatibilities between fillers and polymers that are

Fourier-transform infrared spectroscopic studies of cross-linked human serum albumin microcapsules. 2. Influence of reaction time on spectra and correlation with microcapsule morphology and size.

M C Levy et al.

Journal of pharmaceutical sciences, 83(3), 419-422 (1994-03-01)

Microcapsules were prepared from human serum albumin (HSA) through interfacial cross-linking with terephthaloyl chloride (TC). Reaction times were increased from 2 to 60 min, while pH (9.8) and TC concentration (2.5% w/v) were kept constant. Fourier-transform infrared (FT-IR) spectra of
