抗菌醛鞣透明皮革的制备及性能OA北大核心
Preparation and Properties of Antibacterial Aldehyde-tanned Transparent Leather
以改性戊二醛(GTW)鞣绵羊皮作为原料,通过浸渍法引入丙烯酸单体和纳米银(AgNPs),在热引发条件下原位自由基聚合得到抗菌醛鞣透明皮革.采用扫描电子显微镜、X射线光电子能谱、热重法/微商热重法、差示扫描量热法、万能试验机等对GTW鞣透明皮革进行了微观形貌、结构组成、热稳定性能和物理性能表征.结果表明,该GTW鞣透明皮革具备良好的物理性能,其韧性强度最高能够达到 6 MJ/m3,断裂应力为 21.4 MPa.利用紫外-可见近红外光度计测得GTW鞣透明皮革在 550 nm处的透光率最高,接近 80%,具有良好的透明性.此外,GTW鞣透明皮革的平均柔软度为4.6 mm-1,并且AgNPs的引入赋予了GTW鞣透明皮革优异的抗菌性能和生物相容性.
Antibacterial aldehyde-tanned transparent leather was obtained from modified glutaraldehyde(GTW)-tanned sheepskin by introducing acrylic acid monomer and silver nanoparticles(AgNPs)via impregnation followed by the in-situ free radical polymerization under thermally initiated conditions.The micro-morphology,structural composition,thermal stability and physical properties of the GTW-tanned transparent leather were characterized by scanning electron microscopy,X-ray photoelectron spectroscopy,thermogravimetry/differential thermogravimetry,differential scanning calorimetry and universal testing machine.The results show that the GTW-tanned transparent leather has good physical properties with toughness strength up to 6 MJ/m3 and breaking stress of 21.4 MPa.The highest transmittance of GTW-tanned transparent leather was observed at 550 nm,which was close to 80%,using UV-visible near-infrared(NIR)photometer,and it had good transparency.In addition,the average softness of GTW-tanned transparent leather was 4.6 mm-1,and the introduction of AgNPs conferred excellent antimicrobial properties and biocompatibility to GTW-tanned transparent leather.
