Cross-Linked Cellulose Membranes with Robust Mechanical Property, Self-Adaptive Breathability, and Excellent Biocompatibility
ACS Sustainable Chemistry & Engineering, 2019Co-Authors: Xiaoyu Chen, Jinlian Hu, Lina ZhangAbstract:High-performance breathable bio-based membranes have attracted considerable attention worldwide due to the limited fossil energy resources and the demand for sustainable development. As the most abundant polysaccharide, cellulose is an almost inexhaustible raw material with hydrophilicity, biocompatibility, biodegradability, chemical modifying capacity, etc. that has demonstrated versatile applications. Herein, cellulose membranes (CEMs) with Mechanically strong Property, self-adaptive breathability, and excellent biocompatibility were fabricated by a green technology. The obtained CEMs exhibited an increased integrated Mechanical Property with the broken strength and broken elongation improved from 54.2 to 137.4 MPa and from 4.7 to 18.3%, respectively. Moreover, the obtained cellulose membranes exhibited a self-adaptive breathability with varying temperature and relative humidity (RH), and the water vapor transmission rate (WVTR) of CEMs was much better than that of some famous commercial products, such as 3M-Nexcare. Besides that, cytotoxicity testing results revealed that CEMs were noncytotoxic, with cell viability reaching up to 97%, showing an excellent biocompatibility. Simultaneously, compared to the pristine cellulose membrane, the transmittance and water repellency of cross-linked membranes have been improved to some degree. It is believed that the achieved membranes are effective and scalable products for meritorious applications in medical bandages, wound healing, smart apparels, building materials, and so forth.

self healing hydrogel of poly vinyl alcohol agarose with Robust Mechanical Property
Starch-starke, 2019Co-Authors: Jia Shao, Zheng Zhang, Shixing Zhao, Sui Wang, Yufang HuAbstract:As promising soft materials, various excellent properties of hydrogels have received widespread attention during recent years. Mechanical properties and self‐healing performance are required characteristics for hydrogels in practical applications. An important challenge is to develop hydrogels exhibiting Mechanical performance and self‐recoverability through physical cross‐linking. In this work, the authors report a hydrogel consisting of a fully physically linked poly (vinyl alcohol)/agarose (PVA/AG) dual‐network, which is of high toughness and self‐healing properties. The synthesis process of the PVA/AG hydrogel is convenient, with AG as the first network, and hydrogen bonding and crystal‐associated PVA as the second network to form a dual physical crosslink. Due to this physical cross‐linking, the PVA/AG hydrogel has good Mechanical properties (tensile strength of 6.5 MPa to 14.6 MPa, ductility of 168% to 214%). The highest compressive strength of hydrogel is up to 3.66 MPa, which is almost 8 times that of pure PVA hydrogel. In addition, it has excellent self‐healing properties without stimulation or healing agents. Compared to pure PVA hydrogel, PVA/AG hydrogels have higher thermal stability due to higher decomposition temperatures and lower degradation rates. In this study, the authors also initially explore the potential application of obtained hydrogel.

β tricalcium phosphate poly glycerol sebacate scaffolds with Robust Mechanical Property for bone tissue engineering
Materials Science and Engineering: C, 2015Co-Authors: Kai Yang, Jing Zhang, Yulin Li, Yuan YuanAbstract:Abstract Despite good biocompatibility and osteoconductivity, porous β-TCP scaffolds still lack the structural stability and Mechanical Robustness, which greatly limit their application in the field of bone regeneration. The hybridization of β-TCP with conventional synthetic biodegradable PLA and PCL only produced a limited toughening effect due to the plasticity of the polymers in nature. In this study, a β-TCP/poly(glycerol sebacate) scaffold (β-TCP/PGS) with well interconnected porous structure and Robust Mechanical Property was prepared. Porous β-TCP scaffold was first prepared with polyurethane sponge as template and then impregnated into PGS pre-polymer solution with moderate viscosity, followed by in situ heat crosslinking and freezing–drying process. The results indicated that the freezing–drying under vacuum process could further facilitate crosslinking of PGS and formation of Ca 2 + –COO − ionic complexing and thus synergistically improved the Mechanical strength of the β-TCP/PGS with in situ heat crosslinking. Particularly, the β-TCP/PGS with 15% PGS content after heat crosslinking at 130 °C and freezing–drying at − 50 °C under vacuum exhibited an elongation at break of 375 ± 25% and a compressive strength of 1.73 MPa, 3.7-fold and 200-fold enhancement compared to the β-TCP, respectively. After the abrupt drop of compressive load, the β-TCP/PGS scaffolds exhibited a full recovery of their original shape. More importantly, the PGS polymer in the β-TCP/PGS scaffolds could direct the biomineralization of Ca/P from particulate shape into a nanofiber-interweaved structure. Furthermore, the β-TCP/PGS scaffolds allowed for cell penetration and proliferation, indicating a good cytobiocompatibility. It is believed that β-TCP/PGS scaffolds have great potential application in rigid tissue regeneration.
