Description
技术领域
本发明属于高分子材料技术领域，具体涉及一种具有可控气味播放功能的高分子材料及其制备方法，其具有多层结构、分层制备等特点，其能够依据香精挥发特点及使用环境来调节各层结构特征，从而达到气味气体可控释放的目的。
背景技术
液体香精具有多组分特点，且各组分挥发特性不同，从而导致液体香精自然状态下头香挥发较快，长时间使用后香精气味品质不完全，气味成分缺失，导致香精的使用时间大大减少。单一组分或结构对于液体香精往往仅限于液态存储或气味透过功能，对其可控释放不能达到理想效果，无法有效延长液体香精使用寿命。因此本发明设计多层结构对液体香精气味释放进行多重控制，从而达到气味气体可控播放功能，延长液体香精高品质气味使用寿命。
本发明采用分层控制方法，层层制备，从而达到气味可控播放功能。本发明中精油存储层选用具有高吸附性的高分子多孔材料，其具有较高的孔隙率和液体吸附性能，同时高分子材料对气味分子无选择性吸附或化学反应发生，可有效还原气味品质；气味透过层为溶液电纺丝法制备的高分子纳米纤维层，其宏观状态下为致密薄膜，微观状态下为纳米纤维层，含氟材料自身结构使其具有低表面能特性，纳米纤维薄膜特殊结构使得液体香精自身表面张力的存在无法对纤维层浸润，从而使得液体香精挥发受到一定程度限制，宏观状态下即为有效防止液体香精渗出，同时气味分子可顺利通过，扩散至外表面；气味分子播放层为相转移法制备的微纳结构多孔高分子材料层，材料孔径及分布具有可调性，通过调节孔径大小及表面孔密度，即可调节气味气体透过流量，从而达到气味播放速度可控性。
本发明采用分层控制的方法，所制备材料具有可控气味播放功能，有效延长高品质气味使用时间，提高液体香精使用寿命。
发明内容
本发明的目的是提供一种具有可控气味播放功能的高分子材料及其制备方法，从而延长液体香精使用寿命，提高气味使用效率。
本发明采用的技术方案为分层制备，多重协同控制。具体包括如下步骤：
1、选取直径2mm～50mm，长度5mm～200mm，密度2kg/m3～100kg/m3的高分子圆柱体多孔材料，其材质可为聚氨酯、三聚氰胺、聚乙烯等对小分子无选择性的高分子材料，将其于烘箱中80℃放置6小时除去其所吸收空气中的水分，得到干燥的圆柱体多孔材料作为内层精油存储层待用。
2、配制浓度为1wt％～20wt％的四氟乙烯、六氟丙烯、六氟双酚A型聚芳醚、六氟型聚酰亚胺等含氟高分子材料的单一或混合溶液，溶剂可选择四氢呋喃、N-N’二甲基乙酰胺、N-甲基吡咯烷酮等对材料良性溶剂，完全溶解后采用溶液电纺丝方法制备直径为5nm～200nm的纳米纤维，将制备的纳米纤维旋转涂布于干燥后多孔材料表面，控制其厚度为5μm～1000μm，孔隙率为10％～85％，此纳米纤维层宏观状态为致密薄膜，微观状态为纳米纤维，可有效防止液体香精渗出，同时气味分子亦可顺利通过纳米纤维层扩散至外层。
3、配制浓度为1wt％～30wt％的偏氟乙烯、聚芳醚、壳聚糖等高分子材料溶液，溶剂可选择水、乙醇、四氢呋喃、N-N’二甲基乙酰胺、N-甲基吡咯烷酮等对材料良性溶剂，完全溶解后采用相转移的方法将纳米纤维层包覆后的材料浸润此溶液，浸润时间5s～60s，取出后于空气中静置5s～120s，后浸润于水、乙醇、丙醇、丙二醇等不良溶剂中使高分子层相分离，浸润时间10s～250s，自然晾干后即制得多层结构高分子材料。
4、将白兰地、咖啡、烤肠、桃花、玫瑰等液体香精注射入所制备多层结构材料内层结构中，测试其气味播放效果及重量变化。
本发明通过制备多层结构高分子材料，对气味播放进行可控释放，有效提高液体香精使用效率及寿命。

具体实施方式
下面通过具体实施例来进一步说明本发明，但实施例仅用于说明，并不限制本发明的范围。
实施例1：
1)选取直径4mm、长度20mm、密度8kg/m3的聚氨酯多孔材料，于烘箱中80℃放置6小时除去其吸收的水分，得到干燥圆柱体多孔材料待用；
2)以N-N’二甲基乙酰胺为溶剂配制浓度为10wt％的六氟型聚酰亚胺溶液，采用电纺丝方法将其纺成纳米纤维，电压10kV～12kV，纤维直径控制为50nm～60nm，膜厚度30μm～35μm，孔隙率50％～55％，其宏观状态为致密薄膜，扫描电子显微镜下其微观状态为纳米纤维，可有效防止液体香精渗出，同时气味分子可顺利扩散；
3)配制浓度为5wt％的聚芳醚砜溶液，溶剂为N-N’二甲基乙酰胺，完全溶解后将上述纳米纤维包覆后的材料浸润此溶液中10s，取出后空气中放置5s，后于不良溶剂(蒸馏水)中浸润20s，即制得多层结构高分子材料，孔径为150nm～200nm，厚度100μm～120μm；
4)将300mg白兰地精油注射入多层结构高分子材料中，放置称重，测试其气味播放速度，同时将300mg白兰地精油注射入未经任何处理的同尺寸多孔材料中，同时对比测试两种材料气味品质、气味保持时间，结果表明短时间内两种材料气味品质无明显差别，随着时间增长，普通多孔材料气味品质及气味浓度逐渐下降，高品质气味有效时间为8～10小时，多层结构高分子材料气味品质及气味浓度均表现良好，高品质气味有效时间为42～45小时。
