To develop a small-diameter tissue engineering blood vessel, the silk fibroin (SF)/poly(butylene succinate) (PBS) tubular scaffolds were fabricated via electrospinning. In the electrospinning process, the electrospun SF/PBS composite tubular scaffolds were collected on a 3D collector instead of traditional 2D collector. The effects of 3D collector and process parameters of electrospinning on the morphologies of the tubular scaffolds were investigated. FTIR was used to study the secondary structure of SF. The mechanical properties and the porosities of the tubular fiber materials were characterized. The results showed that SF/PBS composite tubular materials with different sizes and shapes could be prepared by changing the voltage, TCD and the structure of 3D collectors. The porosity, the tensile stress, the elongation at break and the burst pressure of the composite tubular scaffold were 84.6%, 4.31 MPa, 27.85% and 358 kPa, respectively.

Luminescence properties of luminous fiber largely depends on properties of luminescent materials. Therefore, to improve the luminescence performance of luminous fiber, it is necessary to study luminescence properties of luminescent materials. According to the luminous fiber’s requirements for luminescent materials, the particle size, spectral and afterglow properties were studied and analyzed. The results showed that: The phosphor which particle size was 7-8 μm had better afterglow performance, and consistent with the requirements of the luminous fiber. That was the first choice for luminescent materials. The light color of luminous fiber prepared by SrAl2O4:Eu2 +, Dy3 + was yellow-green ,and the change of Eu2 +, Dy3 + content did not lead to blue shift or red shift. To get other light color luminous fiber, types of rare-earth ions must be changed; The H3BO3 content and sintering temperature on the luminescence properties were not independent. They have a certain relevance with each other.

At the same time, Fourier transform infrared spectroscopy and nuclear magnetic resonance spectroscopy and thermal analysis have been used to analysis and discuss the structure of the modified copolyesters. The results of FTIR and 1H-NMR show that the hydrophobically-modified copolyester with chemical bond was formed by FGX and BHET copolymerization, such as by adding 12% of the FGX viscosity 2000CP under low vacuum, the water contact angle of the modified polyester (MPET-12) can be up to 97.2 °,the surface energy of the modified polyester is 23.4mJ/m2, which is close to the FGX’s (20mJ/m2). Due to the small quantities of modifier, the thermal of the hydrophobically-modified copolyester has not changed significantly comparing with Poly(ethylene terephthalate)(PET).

To make bamboo cellulose efficiently utilized, structural characterizations of three hemicelluose fractions isolated by alkaline hydrogen peroxide from defatted bamboo fiber were studied. The results demonstrated that the purity of three fractional hemicelluloses is very high except that the first fractional hemicellulose contains only a little lignin. The three fractional hemicelluloses contain four structural units of xylose, glycuronate, arabinose and galactose, and could be xylan-hemicellulose because of the highest content of xylose up to about 50%. The three fractional hemicelluloses are non-crystal and have great differences in physical structures. The first fractional hemicellulose includes only a sphere, while the second and third fractional hemicelluloses contain irregular polyhedron and white nebulous object. Weight-average relative molecular weight (MW) of hemicellulose gradually decreased because of the deepening fractured-degree of hemicellulose molecular chain with the increasing of fractional grade.
