離子聚合物的合成及其高壓靜電紡絲With increasing the amount of pva in the blend, concentration of spinning solution and the voltage of electrospinning, spinnability of the solution could be favored
研究表明：與聚乙烯醇共混后再生絲素纖維的柔韌性有一定改善，適當增加pva在共混物中的含量、提高紡絲液濃度以及紡絲電壓有利於改善共混溶液的可紡性。This charged fiber can be directed or accelerated by electrical forces and then collected in mats or other useful geometrical forms. the diameters of electrospun fibers are in the range of tens of nanometers to several micrometers. in this paper, polyacrylonitrile ( pan ) nanofibers are made by electrospinning pan / dimethylformamide ( dmf ) and pan / dimethylacetamide ( dmac ) with adjusting the main process parameters including electrostatic voltage ( 20 ~ 50kv ), sprinkler aperture ( 0. 5 ~ 0. 8mm ), collection distance ( 15 ~ 25cm ), solution concentration ( 6 wt % - 14 wt % )
本文主要對聚丙烯腈（ pan ）二甲基甲酰胺（ dmf ） 、 pan二甲基已酰胺（ dmac ）體系進行電紡絲，調節靜電壓（ 20 50kv ） 、噴頭孔徑（ 0 . 5 0 . 8mm ） 、接收距離（ 15 25cm ） 、溶液濃度（ 6wt 14wt ）等過程參數，制得pan納米纖維，纖維平均直徑在200 1000nm ；詳細分析了過程參數對纖維細度、形態等的影響，認為高聚物溶液濃度及靜電壓對纖維細度有決定性影響，其它過程參數如接收距離、噴射孔徑、紡絲溶液溫度、溶液電導率等的調整應以這兩參數為基礎進行。Electrospinning origins from that electrically charged fluid is forced jets in the high voltage electrostatic field. electrospinning occurs when the electrical forces at the surface of a polymer solution or melt overcome the surface tension and cause an electrically charged jet to be ejected. when the jet dries or solidified, an electrically charged fiber remains
電紡絲技術是基於高壓靜電場下導電流體產生高速噴射的原理發展而來，其基本過程是：聚合物溶液或熔體在幾千至幾萬伏的高壓靜電場下克服表面張力而產生帶電噴射流，溶液或熔體射流在噴射過程中乾燥、固化，並保持一定電荷量，最終落在接收裝置上形成纖維氈或其它形狀的纖維結構物。There are basically three components in experimental installation of a high voltage supplier, a capillary tube with a pipette or needle of small diameter and a metal collecting screen
電紡絲技術的基本裝置由高壓直流電源、帶有細小噴絲頭的樣品管和收集板三部分組成。Concentrations, bore flow rate, dope solution temperature, coagulant bath temperature, 5 types of composite pu hollow fiber membranes were prepared. the recovery extent of different composition hollow fiber membrane pore size is different. the ability to recover of type
另外，在pu紡絲液中混入適量醋酸纖維素（ ca ） ，也可有效改善pu溶液的可紡性，提高pu中空纖維膜的支撐強度和耐壓強度，但壓力響應性有所減弱。分享友人
