| 1 | Enhanced flame-retardant performance of poly(lactic acid)(PLA) composite by using intrinsically phosphorus-containing PLA显示文摘The intrinsically phosphorous-containing flame-retardant poly(lactic acid)(P-PLA) was synthesized through the chain extension of L-lactide and 9,10-dihydro-9-oxa-10-phosphaphenanthrene-10-oxide(DOPO) derivative, then P-PLA was melt blended with neat PLA to produce flame-retardant PLA composite(FR-PLA). The flame-retardant properties of FR-PLAs were investigated by Limiting Oxygen Index(LOI), UL-94, and Cone Calorimeter Tests, the results indicated that the flame-retardant properties of PLA composites were significantly improved with the addition of P-PLA due to its excellent ability to carbonize and dilute combustible gases. The LOI value of FRPLA10 composite(consisting of 90 wt% neat PLA and 10 wt% P-PLA) increased from 20.5 to 27.8 and UL-94 rating reached up to V-1, the peak heat release rate and total heat release of FR-PLA composite were lower than those of neat PLA. The flame-retardant mechanism of FR-PLA depended on both condensed and gaseous phases,which was confirmed by the FTIR, Raman and TG-FTIR. Besides, the tensile strength of FR-PLA10 slightly decreased from 72.4 to 61.8 MPa, which met the requirements of most practical applications. Therefore, the modification method used in this work presented a feasible approach to prepare FR-PLA composite with satisfactory mechanical property. | Senlong Yu Hengxue Xiang Jialiang Zhou Meifang Zhu | 2018 | Progress in Natural Science:Materials International2018，28，5： | 8 |
| 2 | Intriguing anti-superbug Cu2O@ZrP hybrid nanosheet with enhanced antibacterial performance and weak cytotoxicity显示文摘In view of it's strong antibacterial function and minor toxicity,cuprous oxide (Cu2O) is frequently used in various broad-spectrum antibacterial reagents.Nonetheless the undesirable effects of superbugs still remain challenging.In this research,a chemical deposition approach is used to prepare a Cu2O@ZrP composite with nanosheet configuration demonstrating excellent dispersibility and antibacterial traits.From systematic analysis,it was inffered that the content of copper in the nanosheet was about 57-188 mg/g while the average thickness of the nanosheets Cu2O formed on ZrP is approximately 0.8 nm.The results of the minimal inhibitory concentration (MIC) revealed that an extremely low loading of Cu2O in Cu2O@ZrP nanosheet can lead to exceptional antibacterial activity.Examined on two various superbugs;i.e.methicillin-resistant staphylococcus aureus (MRSA) and vancomycin-resistant enterococcus (VRE),the composite nanosheet reagent performed over 99% microbial reduction.More intesetingly,the cell growth rate of the Cu2O@ZrP nanosheet was determined to be 20% lower than that of the neat Cu2O,manifesting a weaker cytotoxicity.This unique hybrid nanosheet with intriguing anti-superbug performance promises highly efficient protection for the fabrics,battledress,and medical textiles. | Jialiang Zhou Hengxue Xiang Fatemeh Zabihi Senlong Yu Bin Sun Meifang Zhu | 2019 | Nano Research2019，12，6： | 7 |
| 3 | Flame retardancy of polyamide 6 hybrid fibers:Combined effects of α-zirconium phosphate and ammonium sulfamate显示文摘Synergistic effect between α-zirconium phosphate(α-ZrP) and ammonium sulfamate(AS) for enhanced flame retardant properties of Polyamide 6(PA6) was investigated by using oxygen index instrument,cone calorimeter,thermogravimetric analyzer(TGA),Instron universal test machine and scanning electron microscopy(SEM).PA6/AS/α-ZrP ternary hybrid materials with various contents of α-ZrP and AS were fabricated by melt-mixing method.The result from flammabihty indicated that the Limiting oxygen index(LOI) and Underwriters Laboratories-94(UL-94) rating of PA6/AS/α-ZrP were significantly accelerated under the coordinating function of α-ZrP and AS.Moreover,the thermal stability for PA6/AS/α-ZrP studied by TGA also demonstrated this synergistic effect between α-ZrP and AS on the heat resistance.The effects of the usage amount of α-ZrP and AS on mechanical properties were analyzed by using uniaxial tensile test.It was found that the addition of AS provided negative effects on the tensile strength of PA6/AS/α-ZrP,however,the adverse trends that mentioned above could be overcome by using the well dispersed α-ZrP. | Hengxue Xiang Lili Li Wei Chen Senlong Yu Bin Sun Meifang Zhu | 2017 | Progress in Natural Science:Materials International2017，27，3： | 7 |
