Facile Synthesis of Thermoplastic Polyamide Elastomers Based on Amorphous Polyetheramine with Damping Performance.

Jie Jiang, Qiuyu Tang, Xun Pan, Jinjin Li, Ling Zhao, Zhenhao Xi, Weikang Yuan,

Novel thermoplastic polyamide elastomers (TPAEs) consisting of long-chain semicrystalline polyamide 1212 (PA1212) and amorphous polyetheramine were synthesized via one-pot melt polycondensation. The method provides accessible routes to prepare TPAEs with a high tolerance of compatibility between polyamide and polyether oligomers compared with the traditional two-step method. These TPAEs with 10 ... Read more >>

Analysis of Bubble Growth in Supercritical CO2 Extrusion Foaming Polyethylene Terephthalate Process Based on Dynamic Flow Simulation.

Shun Yao, Yichong Chen, Yijie Ling, Dongdong Hu, Zhenhao Xi, Ling Zhao,

Bubble growth in the polymer extrusion foaming process occurs under a dynamic melt flow. For non-Newtonian fluids, this work successfully coupled the dynamic melt flow simulation with the bubble growth model to realize bubble growth predictions in an extrusion flow. The initial thermophysical properties and dynamic rheological property distribution at ... Read more >>

A comparable study of polyglycolic acid's degradation on macrophages' activation.

Jiapeng Zhang, Bowen Xie, Zhenhao Xi, Ling Zhao, Lian Cen, Ying Yang,

Polyglycolic acid (PGA) is a faster biodegradable polymer for various implants, frequently causing different macrophages' activation. In this study, we undertook a comparable study of PGA's degradation on macrophages' activation with different PGA crystallinity (in porous and fibrous 3D scaffolding format) in an in vitro and in vivo model. The ... Read more >>

A mussel-inspired carboxymethyl cellulose hydrogel with enhanced adhesiveness through enzymatic crosslinking.

Yujie Zhong, Jie Wang, Zhenyu Yuan, Yu Wang, Zhenhao Xi, Li Li, Zhiyong Liu, Xuhong Guo,

In order to replace conventional sutures in wound closing applications, favorable hydrogels with strong wet tissue adhesion and biocompatibility have attracted considerable attention. Herein, inspired by mussel adhesive protein, a series of dopamine modified carboxymethyl cellulose (CMC-DA) hydrogels were prepared in situ using enzymatic crosslinking in the presence of horseradish ...

Novel Fabricating Process for Porous Polyglycolic Acid Scaffolds by Melt-Foaming Using Supercritical Carbon Dioxide.

Jiapeng Zhang, Shengbing Yang, Xi Yang, Zhenhao Xi, Zhenhao Xi, Ling Zhao, Lian Cen, Eryi Lu, Ying Yang,

Polyglycolic acid (PGA) is a biocompatible and biodegradable polymer with high crystallinity. It is difficult to obtain PGA porous scaffolds with controllable morphology as well as outstanding mechanical properties without toxic solvents. The current study thus aimed to develop a novel melt-foaming strategy to prepare porous PGA scaffolds through the ... Read more >>
