Fibroin Solution

The native silk fibroin fiber from Bombyx mori has been used as suture with non-degradable character. Therefore, preparing biodegradable silk fibroin fiber is very attractive and important. In this paper, the biodegradable silk fibroin fiber with high strength was prepared according to the process of regenerated silk fibroin fiber from the 1,1,1,3,3,3-hexafluoro-2-propanol (HFIP) solution and by adding calcium chloride CaCl2 to the silk fibroin solution. The degradation rate of the regenerated silk fibroin fibers was dependent on calcium chloride concentration.

Fibroin Solution

Carbon nanotube (CNT) is a new type of nanoscale materials, which has excellent adsorption and mechanical properties. In this paper, carbon nanotubes were added in the regenerated silk fibroin solution to get CNTs/silk fibroin composite fiber, which had more excellent mechanical property than the regenerated fibroin fiber. The results indicate that the optimum preparation conditions are summed up as follows: silk fibroin concentration 35%, spinning temperature 40oC, carbon nanotube mass fraction 1.0% and the longest storage time less than 7 days. The mechanical property of regenerated fibroin fiber which added with carbon nanotubes is obviously improved.

Fibroin Solution

In the present study, silk fibroin solution was controlled through a simple shearing to accomplish the steady and rapid gelation process and the conformational transition. Antheraea yamamai silk fibroin was formed into hydrogels quicker than Bombyx mori silk fibroin on the same condition. Comparing with Bombyx mori silk fibroin, the rapid gelation of Antheraea yamamai silk fibroin was concerned with its alternate polyalanine-containing units which are tended to form the ?-helix structures spontaneously. The entropic cost during the conformational transition to ?-sheet is less than that from random coil to ?-sheet.

Fibroin Solution

The multiwalled carbon nanotubes (MWCNTs) incorporated organic silk fibroin cryogels were fabricated through sol-gel process of aqueous silk fibroin solution, followed by freeze-drying. The MWCNT incorporated silk fibroin hydrogel was prepared by the regeneration of silk fibroin using an aqueous silk fibroin solution in which MWCNTs were dispersed by in-situ methods. The morphology and microstructure of the silk fibroin network structure were characterized using field emission scanning electron microscopy (FESEM) and transmission electron microscopy (TEM). The FESEM and TEM images show that the cryogels had three-dimensional network structures and the MWCNTs were well embedded in the network structures of regenerated silk fibroin. The porous properties of the MWCNT incorporated silk fibroin cryogels were investigated by nitrogen adsorption-desorption technique. The MWCNTs increased the proportions of micropores and mesopores in the silk fibroin cryogels when they were introduced in the appropriate amounts.

Fibroin Solution

The thermal properties and rheological behavior of concentrated regenerated silk fibroin aqueous solution from 15% to 37% was investigated by differential scanning calorimetry (DSC) and rheometer. Also the conformation of solutions was characterized by Raman spectra. It was discovered that the major endothermic peak in the DSC curves shifted toward the lower temperature region with increasing the concentration. This behavior suggests increasing the concentration can accelerate conformational transition of silk fibroin from random coil and α-helix to β-sheet structure. In addition, it was found that the viscosity of solution increased with increasing concentration in favor of spinning.
