一般描述

缩水甘油基三甲基氯化铵(GTMAC)是一种阳离子化剂,通常用于淀粉改性。

应用

缩水甘油基三甲基氯化铵可用作衍生剂,与壳聚糖反应合成N-(2-羟丙基)-3-三甲基氯化铵壳聚糖(HTCC),一种水溶性壳聚糖衍生物。HTCC可与银纳米颗粒形成纳米复合膜,该膜具有良好的抗菌特性和光透明性。阳离子淀粉还可通过用GTMAC衍生淀粉来制备。

包装

1 L in glass bottle

The electrospinning PAN nanofiber membrane (P-CN) was hydrolysed to convert carboxylic groups as reaction sites and covalently graft chitosan molecule. The chitosan derivatives with quaternary ammonium groups exerted greater efficiency against bacteria as compared to pure chitosan. Hence, the chitosan...

The main focus of this work was to establish a correlation between surface topography and chemistry and surface colonization by lactic acid bacteria. For this reason, we chose gold substrates with different surface architectures (i.e., smooth and nanorough) that were...

Oxidized multi-walled carbon nanotubes (oxCNTs) were functionalized by a simple non-covalent modification procedure using quaternized hyperbranched poly(ethyleneimine) derivatives (QPEIs), with various quaternization degrees. Structural characterization of these hybrids using a variety of techniques, revealed the successful and homogenous anchoring of...
