请参阅图1-2,本发明提供一种技术方案:一种角蛋白和尼龙66纳米纤维膜制备方法,包括:
包括以下步骤:
步骤一,称取一定量的角蛋白粉末,利用六氟异丙醇溶剂配置成一定浓度的角蛋白溶液;
步骤二,称取一定量的尼龙66,利用六氟异丙醇溶剂配置成一定浓度的尼龙66溶液;
步骤三,再将所述步骤一和步骤二得到的溶液进行混合后静置脱泡得到混合溶液,得到的混合溶液即为纺丝溶液;
步骤四,再将步骤三得到的混合溶液通过静电纺丝机器利用静电纺丝技术,制备出复合纳米纤维。
步骤一中,角蛋白粉末采用猪蹄甲角蛋白进行制备。
步骤一中,将角蛋白粉末用六氟异丙醇溶解得到角蛋白溶液浓度为4%。
步骤二中,将尼龙66用六氟异丙醇溶解得到尼龙66溶液浓度为12%。
步骤三中,将两种溶液进行混合得到纺丝溶液,其角蛋白溶液与尼龙66溶液的体积比为1:1。
步骤四中,静电纺丝机的电压设定25 kv,接受距离是12 cm,纺丝流量是0.2 ml/h。
首先从废弃资源中提出出可再利用的角蛋白资源,再将配置成角蛋白溶液,再将其他待纺溶液加入到角蛋白溶液中混合均匀后得到纺丝溶液,通过静电纺丝技术,静电纺丝出纳米纤维纤维,制备的纺丝溶液必须具备下列条件:角蛋白的分子量不能太小;用于混合的的高分子材料不能与角蛋白发生变性反应;纺丝制备出的复合纤维机械性能要比纯的高分子材料纺丝出的纤维强度大。
静电纺丝技术的主要操作流程是:将制备好的纺丝溶液加入到注射器中,再将注射器固定并且连接上电源后,纺丝溶液会在外力作用下被从注射器中推出,并且当电源调节到足够大时,纺丝溶液会细丝状喷射在接收板上,随着时间的推移,接收板上会逐渐形成一层纤维膜,其中,装置中的电源一般采用正负极双电源,注射器一般是玻璃注射器,接收板一般采用的是铝箔纸。
工作原理:该角蛋白和尼龙66纳米纤维膜制备方法,是分别称取一定量的角蛋白粉末和PA66溶解于六氟异丙醇中,角蛋白溶液浓度为4%,再配置质量分数12%的PA66溶液,然后将两种溶液混合均匀得到纺丝溶液,配置的纺丝溶液放置在磁力搅拌器上搅拌1 h后静置脱泡,再将脱泡后的纺丝溶液倒入10 ml的注射器中,在静电纺丝机上制备纳米纤维膜,室温下纺丝至铝箔上有一定厚度的纳米纤维膜,静电纺丝机的电压设定25 kv,接受距离是12 cm,纺丝流量是0.2 ml/h,增加了整体的实用性。
