摘　　要：纳米银是一种由银原子或银离子组成的超微颗粒,具有优异的抗菌能力。结冷胶是一种多糖物质,有较好的水溶性,能够在加热和冷却后形成凝胶。本研究制备了掺杂0.2mL、0.4mL、0.6mL、1.0mL纳米银的结冷胶,评估其成型情况。结果表明,随着纳米银掺杂量的增加,结冷胶的成型效果和自身性能逐渐下降。基于结冷胶的成型情况,选取掺杂0.6mL纳米银的结冷胶进行性能测试研究,并利用SEM-EDS检测银粒子在不同相对吸收性纸张上的释放情况。结果表明,银粒子能够成功进入并分散在结冷胶内,测试纸张的内部成分中均有一定比例的银元素,纸张上有银粒子的附着;纸张的相对吸收性大小与纸张内部中的银元素含量呈正相关,即纸张的相对吸收性越大,释放到纸张上的银粒子含量越高。本文为研究多功能材料、提升结冷胶的抗菌性能以及在各领域的应用提供了相关的实践参考。Nanosilver is an ultramicro particle composed of silver atoms or ions,which has excellent antibacterial ability.Gellan gum is a polysaccharide substance with good water solubility,capable of forming gels upon heating and cooling.In this study,gellan gums doped with 0.2mL,0.4mL,0.6mL,and 1.0mL of nanosilver were prepared to evaluate their molding.The results showed that the molding effect of the junction-cooled gels and their own properties gradually decreased with the increase of nanosilver doping.Based on the molding situation of the jellied cold adhesive,the jellied cold adhesive doped with 0.6mL of nanosilver was selected for the performance test study,and the release of silver particles on different relative absorbent papers was detected using SEM-EDS.The results show that the silver particles can successfully enter and be dispersed within the gel,the internal composition of the test paper have a certain proportion of silver elements,and there are silver particles attached to the paper;the size of the relative absorbency of the paper is positively correlated with the content of silver elements within the paper,i.e.,the larger the relative absorbency of the paper,the greater the content of the silver particles released onto the paper.This paper provides relevant practical references for the study of multifunctional materials,the enhancement of antimicrobial properties of knotted cold glue and its application in various fields.
