生物可降解静电纺PBST超细纳米纤维的制备及工艺研究
Study on preparation technology of ultrafine biodegradable electrospun PBST nanofibers
摘要
Abstract
The spinnability of poly(butylene succinate terephthalate)(PBST)in a mono-solvent system of dichlorometh-ane(DCM)or in a binary solvent system of chloromethane/N,N-dimethylformamide(DMF)was intensively investigat-ed by using a solution electrospinning technique.The effects of polymer spinning solution concentration,feeding rate,and solvent ratio on the diameter of PBST nanofibers during the electrospinning process were also investigated.The di-ameter of the PBST nanofibers was further evaluated by the addition of a tetrabutylammonium chloride(TBAC)organic salt during the electrospinning process.The assistance effects of TBAC on different concentrations or solvent systems were also studied.The results indicated that the addition of TBAC could greatly elevate the conductivity of the polymer solution,improving its spinnability and consequently reducing the fiber diameter.Meanwhile,the filtration properties of the as-prepared PBST nanofibrous materials were also preliminarily explored.The PBST nanofibrous materials with a minimum fiber diameter of 65 nm were prepared by using a 5-wt%PBST/(DCM/DMF=7/3)polymeric solution,in which the mass ratio of PBST to TBAC was 4/1.The PBST nanofibrous materials obtained an optimal filtration effi-ciency of 99.98%and a filtration resistance of 237 Pa when using an 8-wt%PBST/(DCM/DMF=7/3)polymeric so-lution,in which the mass ratio of PBST to TBAC was 16/1.关键词
