Electrospinning of chitosan solutions with poly(ethylene oxide) (PEO) in an aqueous solution of 2 wt% acetic acid was studied. The properties of the chitosan/PEO solutions, including conductivity, surface tension and viscosity, were measured. Morphology of the electrospun chitosan/PEO was observed ...
Chitosan solution was obtained by dispersing 1.5% (w/v) in an aqueous solution of acetic acid at 2% (v/v). The solution was mechanically stirred until solubilization. After that, 25 g of solution was poured into Petri dishes (diameter = 8.2 cm) and dried at room temperature (...
aPH adjustment of the chitosan solutions from the solubilization to pH 2 was realized with acetic acid solution and hydrochloric acid was used for pH below 2. chitosan解答的酸碱度调整从可溶化到酸碱度2体会用乙酸解答,并且盐酸为酸碱度使用了在2以下。 [translate] ...

A variety of substituted amines reacted with chloroacetyl chloride (at molar ratio of 1:1.2) in CH2Cl2system in ice bath for 1 h to obtain corresponding benzothiazole amides [44]. Preparation of NSCS and BTL-11@NSCS NPs CS (1.0 g) was dissolved in 200 mL of 1% acetic acid solution (in...
1) chitosan acetic acid normal saline solution 壳聚糖醋酸生理盐水溶液 1. It was found that the red blood cells were accumulated and deformed after posting inchitosan acetic acid normal saline solution. 本工作研究了不同脱乙酰度和不同分子量壳聚糖、壳聚糖醋酸生理盐水溶液及羧甲基壳聚糖生理盐水溶液的凝血...
by decomposition and deacetylation of chitin as a raw material; and passing the crude reactant solution through an inline mixer while sequentially continuously a pH-adjusting agent and acetic acid anhydride into the inline mixer, so that the crude reactant solution is subjected to acetylation ...
First, we cast a chitosan solution (4 wt % chitosan in 4 wt % acetic acid aqueous solution) on a polyethylene terephthalate (PET) support and then immediately immersed it into a Zn2+-saturated NaOH solution (0.6 wt % Zn2+) to obtain the chitosan-Zn membrane. Next, we rinsed the ...
reaction in homogenous system of anhydrous alcohol without pyridine.The deacetylation degree,crystalline properties and infrared spectrum were respectively characterized by means of acid-base titration,XRD and IR.And the molecular structure and water-solution mechanism of water-soluble chitosan were discussed...
Subsequently, a solution of chitosan (0.24 mg/mL) in 1% acetic acid, previously prepared and kept under agitation for 12 h to solubilize the polymer was added and the mixture was kept under agitation overnight to enable the formation of nanospheres. The final concentrations of imazapyr ...
