提供了纳米纤维‑纳米线复合物及其生产方法。所述方法包括使用偶极溶剂制备纳米颗粒，通过静电纺丝在包含该纳米颗粒的静电纺丝合成溶液中生产纳米纤维‑纳米颗粒复合物，以及通过水热合成干燥的纳米纤维‑纳米颗粒复合物，从纳米颗粒生长纳米线。

Description

纳米纤维-纳米线复合物及其生产方法
技术领域
本公开涉及纳米复合物(nanocomposites)，更具体地涉及通过如下生产的复合物：将包含金属氧化物纳米颗粒的纳米纤维合成至生物可降解聚合物溶液，并通过水热法从纳米纤维生长金属氧化物纳米线。纳米复合物可应用于各种领域，例如光催化剂、传感器、美容保养、基因转移和治疗。
背景技术
纳米纤维具有直径为约1μm或更小的结构。纳米纤维的比重轻，具有非常大的单位质量表面积和微细空间。纳米纤维已应用于各个领域，例如航天工业、燃料电池、电容器、电池、药物递送和生物传感器。特别是由于与细胞的相容性非常高，因此生物可降解纳米纤维被应用于各个领域，包括医学领域(如缝合、组织再生、生物传感器、药物递送和干细胞培养)以及化妆品领域(如面膜)。
已经使用诸如静电纺丝、自组装和相分离的方法生产了纳米纤维。自组装是用于无刺激的分子自发组建的方法。然而，自组装在合成条件方面敏感，包括复杂的合成程序并显示出低的产率。相分离是通过短时间段冷却聚合物溶液来合成纤维的方法。尽管相分离比自组装更简单，但它受到聚合物类型的限制。相比之下，静电纺丝比其它合成技术简单得多，比起其它合成技术显示出更高的产率，并且不受聚合物类型的限制。
水热法被用作从无机纳米颗粒生长成纳米线的简单方法。在锌氧化物的情况下，在大致90℃的温度下合成是可能的。水热法具有可在低温下在各种基材上批量生产的优点。
传统地，浸涂主要用作制造两种材料的复合物的方法，例如纳米线结合至纳米纤维的形式。在浸涂中，通过将纳米纤维在含纳米颗粒的溶液中浸渍预定时间来固定颗粒。然而，由于颗粒被简单地固定在表面上，因此浸涂导致额外的工序和不一致的纳米颗粒分布。
因此，需要用于生产两种类型材料的复合物(例如纳米线结合至纳米纤维的形式)的新方法。
发明内容
技术问题
本公开的示例的实施方式提供了通过静电纺丝合成含有纳米颗粒的纳米纤维的方法，该方法通过将锌氧化物纳米颗粒注入生物可降解聚合物合成溶液中，并且通过水热法从处于纳米纤维内部和纳米纤维表面上的锌氧化物纳米颗粒生长锌氧化物纳米线。
本公开的示例的实施方式提供了用于调节纳米线的密度并且通过调节待注入的纳米颗粒的量在空间上均匀地生长纳米线的方法。纳米纤维-纳米线复合物的最重要的问题是均匀性，该问题通过溶剂调节来解决。
技术方案
根据本公开的示例的实施方式，用于生产纳米纤维-纳米线复合物的方法包括：使用偶极溶剂制备纳米颗粒；通过静电纺丝在包含纳米颗粒的静电纺丝合成溶液中生产纳米纤维-纳米颗粒复合物；以及通过水热合成干燥的纳米纤维-纳米颗粒复合物，以从纳米颗粒生长纳米线。
在本公开的示例的实施方式中，纳米颗粒可以是金属氧化物纳米颗粒，并且纳米纤维可以包含生物可降解聚合物。
在本公开的示例的实施方式中，上述金属氧化物纳米颗粒可以是锌氧化物(ZnO)纳米颗粒。制备纳米颗粒可以包括：将锌氧化物前体溶解在偶极溶剂中以制备锌氧化物前体溶液；在40℃至60℃之间的温度下加热作为阳离子表面活性剂的十六烷基三甲基溴化铵((C16H33)N(CH3)3Br)和锌氧化物前体溶液；将氢氧化钠(NaOH)溶于偶极溶剂中，以制备并在40℃至60℃之间的温度下加热氢氧化钠溶液；通过将氢氧化钠溶液与混合有阳离子表面活性剂的锌氧化物前体溶液混合并使混合溶液在40℃至60℃之间的温度下反应来沉淀纳米颗粒；以及用清洗剂清洗沉淀的纳米颗粒并干燥经清洗的纳米颗粒以提取锌氧化物纳米颗粒。
在本公开的示例的实施方式中，通过静电纺丝在包含纳米颗粒的静电纺丝合成溶液中生产纳米纤维-纳米颗粒复合物可以包括：将纳米纤维合成聚合物溶解在有机溶剂中以生产静电纺丝复合溶液；将干燥的纳米颗粒溶解在偶极溶剂中；将纳米颗粒分散在偶极溶剂中；将包含纳米颗粒的溶液注入静电纺丝复合溶液中，并搅拌经注入的溶液与静电纺丝复合溶液；以及使用静电纺丝装置从静电纺丝复合溶液生产纳米纤维-纳米颗粒复合物。纳米纤维合成聚合物可以是聚(L-丙交酯)(PLLA)聚合物，并且有机溶剂可以是氯仿(CHCl3)。
在本公开的示例的实施方式中，通过水热合成经干燥的纳米纤维-纳米颗粒复合物以从纳米颗粒生长纳米线可包括：将纳米纤维-纳米颗粒复合物添加至包含锌氧化物前体和六亚甲基四胺(HMTA)的纳米线合成水性溶液。
在本公开的示例的实施方式中，锌氧化物前体可以是六水合硝酸锌(Zn(NO3)2+6H2O)。纳米线合成水性溶液可以包含氯化铵(NH4Cl2)和聚乙烯亚胺(H(NHCH2CH2)nNH2)(PEI)。
在本公开的示例的实施方式中，偶极溶剂可以包括乙醇、甲醇、二甲基甲酰胺(DMF)和四氢呋喃(THF)中的至少一种。
在本公开的示例的实施方式中，生物可降解聚合物可以包括聚(L-丙交酯)(PLLA)、聚羟基丁酸酯(PHB)、聚氨酯(PU)和聚碳酸酯(PC)中的至少一种。
在本公开的示例的实施方式中，纳米纤维可以由熔点高于或等于90℃至95℃的聚合物合成。
发明效果
与生产纳米纤维-纳米线复合物的方法相关的代表性的传统方法是浸涂。通过将纳米纤维浸入包含纳米颗粒的溶液中固定的时间段，将纳米颗粒附着于纳米纤维的表面。上述方法是最基本的方法并且可以容易地实施，这是一个优点。但是，上述方法遇到如下缺点。其中一个缺点是制备纳米颗粒溶液。应制备分隔开的溶液，以将纳米颗粒均匀地附着至纳米纤维相同的时间段。这增加了在制备纳米颗粒溶液期间的纳米颗粒的不均匀附着和污染的可能性。此外，由于纳米颗粒的量根据溶液的浸渍时间来确定，因此调节密度并不容易。由于这些现象，接受浸涂的纳米纤维的稳定性降低。这可以通过额外实施用于结构稳定性和纳米颗粒固定化的热处理来克服。
本公开的示例的实施方式提供了能够克服上述缺点的方法。根据该方法，纳米颗粒不是简单地附着至纳米纤维，并且纳米纤维-纳米颗粒复合物可以容易地生产。
根据本公开的示例的实施方式，使用偶极溶剂(例如乙醇)以将纳米颗粒分散到聚合物合成溶液中。偶极溶剂可以允许纳米颗粒均匀地分散在溶解了聚合物的有机溶剂中。纳米纤维-纳米颗粒复合物可以通过对聚合物合成溶液进行静电纺丝来生产。在锌氧化物纳米颗粒的情况下，纳米线可以使用水热法生长。
根据本公开的示例的实施方式，不对纳米纤维-纳米颗粒复合物实施额外的处理即可生长纳米线。通过克服可能发生在浸涂中的纳米颗粒的不均匀分散和溶液污染，可以生产均匀的纳米线。
另外，根据本公开的示例的实施方式的纳米纤维-纳米线复合物通过使用生物可降解聚合物而具有生物友好性，并随着时间的流逝在活体中分解。由于纳米纤维-纳米线复合物对人体无害并具有细胞相容性，因此可将其应用于各种生物医学领域，例如医学材料、组织再生、生物传感器、药物递送和化妆品。此外，纳米纤维-纳米线复合物可以根据纳米颗粒和纳米线特性(可能是复杂的)而被应用于各领域。

具体实施方式
根据本公开的示例的实施方式，纳米纤维-纳米颗粒复合物在向其中注入纳米颗粒的静电纺丝合成溶液中合成。纳米纤维-纳米颗粒复合物通过如下转化为终产物纳米纤维-纳米线复合物，经由水热法从暴露至纳米纤维-纳米颗粒复合物的表面上的纳米颗粒生长纳米线。在通过对纳米颗粒在其中均匀分布的静电纺丝合成溶液进行静电纺丝而获得纳米纤维-纳米颗粒复合物(在其中均匀地包含纳米颗粒)之后，可以通过水热法容易地生产纳米纤维-纳米线复合物。
根据本公开的示例的实施方式，不需要在常规方法中实施的额外的加工，例如热处理。也就是说，可以生产比通过常规方法生产的复合物具有更高生产率和均匀性的复合物。
