Electrospun poly results

Experimental results indicate that the diameter of the fiber produced by electrospinning is influenced by the polymer concentration and molecular conformation,such influence is, described by the Berry number, B, on an electrospun poly (L-lactic acid]/chloroform system gives the following equation ... 

Intensive research effort has been focused on using nanoscale structures to significantly improve the performances (sensitivity, selectivity, response and recovery speed) of the SAW sensors. Liu et al. [39] reported that dynamic chemical vapor SAW sensors have been developed by depositing electrospun polyethylene oxide nanofibrous membranes on the surface of ST-cut quartz the response time of the sensors was 5 min (Fig. 11.2a). Lin [42] constructed a SAW humidity sensor by casting polyaniUne/poly(vinyl butyral) nanofibers on SAW resonator the as-prepared sensor could detect 0.5 % relative humidity in 1 s. Electrospun poly(vinyl pyrrolidone) (PVP)/LiTa03 composite nanofibrous membranes were coated onto the surface of SAW electrode to assay H2 the results indicated that the sensors sensitivity, response time, and recovery time could be remarkably improved and reached 1 %, 120, and 200 s by regulating the electrospinning parameters [43]. 

The electrospinning of poly(s-caprolactone) (PCL) solutions have been reported by Reneker et al. [74]. They varied the PCL solution concentrations between 14 and 18 wt%. The instability in the electrospinning of PCL results in the contact and merging of segments in different loops of the electrospinning jet to form garlandlike fibrous structures [74]. Yoshimoto et al. [75] have studied the potential of electrospun PCL fiber mats for use in bone tissue engineering. They found that the...
