技术领域
本发明总体上涉及成膜组合物、水可分解的膜、以及制备成膜组合物和膜的方法,所述成膜组合物和膜包含含有一个或多个羟基的聚硅氧烷和含有含氮重复单元的聚合物。
背景技术
膜和成膜组合物具有医疗保健应用。例如,它们可以用于服装、帷帘、伤口敷料、绷带、贴片、和医疗装置,例如电极。膜可以应用于健康和受损的皮肤。它们可以保护皮肤和伤口免受微粒、细菌污染、和磨损。应用后,膜必须随后从皮肤上去除。因此,膜必须具有足够的粘附性以在皮肤上保持足够长的时间,从而达到期望的结果,在特定应用中抵抗降解,并且不会对患者造成不利影响。例如,膜必须抵能够抗伤口敷料中生物流体的降解,并且能够在适当时从皮肤上去除,而不会对患者的皮肤造成疼痛、刺激或损伤。对于受伤的皮肤和老年患者的皮肤,不损伤皮肤是特别必要的。
除了粘合性和稳定性之外,膜或成膜组合物可能还需要作为添加剂的合适基质。例如,药物活性物质、抗微生物剂、抗菌剂、抗氧化剂、和/或导电添加剂可能需要合适的基质。
有机聚合物在膜和成膜组合物方面存在问题。它们提供了良好的粘合特性,但可能难以从皮肤上去除,造成损伤,可能含有刺激性或致敏性单体,并且不适合作为某些材料的基质。聚硅氧烷材料也已经用于医疗保健应用中的膜和成膜组合物中。尽管聚硅氧烷提供了良好的从皮肤上去除的特性,但是它们在水分管理、亲水性和透明度方面存在问题。报道了有机物和聚硅氧烷聚合物的组合存在不相容性问题。
因此,需要与一系列活性物质相容的膜和/或成膜组合物,提供足够的粘合强度以根据应用的需要保留在皮肤上,但可以容易地去除,并且在皮肤上或去除时不会对皮肤造成不利影响。
发明内容
本发明涉及一种成膜组合物,其包含以下项的共混物:i)含有一个或多个羟基的聚硅氧烷;ii)包含含氮重复单元的聚合物,其中所述含氮重复单元是酰胺、叔胺、苄胺、或杂环胺;和iii)任选地,溶剂;其中所述成膜组合物形成水可分解的膜。
本发明进一步涉及一种膜,其包含:i)包含一个或多个羟基的聚硅氧烷;和ii)包含含氮重复单元的聚合物,其中所述含氮重复单元是酰胺、叔胺、苄胺、或杂环胺;其中所述膜是水可分解的。
本发明仍进一步涉及一种包含所述膜或成膜组合物的可穿戴产品。
本发明仍进一步涉及一种成膜组合物的制备方法,所述方法包括将包含一个或多个羟基的聚硅氧烷、包含含氮重复单元的聚合物(其中所述含氮重复单元是酰胺、叔胺、苄胺或杂环胺)、以及任选地溶剂组合,并混合直至形成共混物。
本发明的成膜组合物提供了与多种成分相容的基质,并且可以形成具有良好粘合强度的膜,所述膜不刺激、损伤、或使皮肤致敏。本发明的膜用水很容易从皮肤上去除,而不会对皮肤造成损伤或刺激。

实例中使用的方法
成膜组合物的制备
成膜剂的溶液通过将聚硅氧烷和包含胺基重复单元的聚合物与异丙醇(50重量%)混合直到获得均质的配制品来制备。一些聚合物如Luviskol Plus、Gaffix VC-713和PVP/VA E-735以溶液形式提供,因此无需添加附加溶剂。表2和表3包含实例中使用的流体和聚合物的详细信息。表4包含成膜组合物的组成。
膜的形成
使用自动迈拉(Myler)下拉棒和不锈钢垫片将成膜剂的溶液涂覆到50μm厚的聚酯(迈拉)片材上。改变垫片厚度以获得厚度范围从25-50μm的膜。然后将涂覆的片材在烘箱中在130℃下热处理4min以去除溶剂。然后将涂覆的迈拉切成25cm宽的条。在涂覆的24小时内对条进行评估。
水可分解性
在1分钟的过程中,将涂覆的条浸入1L的室温水罐中60次。然后目视检查涂层的外观和形貌变化。将涂覆的条置于玻璃板上,使涂层面朝上并且手指沿着条的长度移动。如果表面表现出润滑性或目视观察到涂层均匀性的变化(透明度、内聚性、表面特征等),则认为所述膜是水可分解的。不溶性膜是表面保持完整、透明且未观察到形貌变化的膜。
膜内聚力和粘着性
将涂覆的条置于载玻片顶部,使涂层面朝上。将条向下压,使得在表面上纵向存在25cm的间隙。通过用食指接触暴露的25cm间隙内的条带表面,并在1秒钟内将其移除来评估内聚性和粘着性。如果很少或没有残留物转移到食指上,则认为膜具有内聚性。无内聚性膜是膜失去完整性并且大部分转移到皮肤上的膜。粘着性值是根据感知的粘着性确定的:1(无粘着性),2(轻微粘着性),3(中等粘着性),4(良好的粘着性)和5(极好的粘着性)。内聚破坏的膜被赋予5的值。
从皮肤释放
将涂覆膜的条置于前臂上,涂层面向皮肤。使膜在皮肤上停留5分钟。之后,通过抓住膜的一端并以180°的角度拉扯,直到在2秒内将整个膜去除来剥离膜。从人类皮肤释放的温和性通过赋值来评估:0(无内聚性,有残留),1(侵蚀性),2(中度侵蚀性),3(可接受),4(良好),5(优秀)。
柔性
将涂覆膜的条对折五次。脱层、破裂或表现出机械故障迹象的膜被认为未通过测试。保持其结构特性的膜被认为是柔性的。
均质性
目视观察涂覆膜的条。光学透明膜被认为是均质的。具有不透明度或混浊度的内聚膜被认为是可混溶的。
玻璃化转变温度评估
使用配备液氮冷却器的TA2500差示扫描量热仪测量聚合物-硅酮共混物的玻璃化转变温度。通过将4-14mg的共混物放入Tzero铝样品盘中制造样品。样品在玻璃化转变温度以上退火五分钟以消除热历史,并且然后以10℃/min冷却至-180℃。以10℃/min加热获得热流曲线,再根据热流曲线使用半高热容法确定玻璃化转变温度。将结果与由Fox方程(1)预测的玻璃化转变温度进行比较:
(1)
其中Tg是共混物、纯聚合物和纯硅酮的玻璃化转变温度,以开尔文为单位,并且w是共混物中聚合物和硅酮组分的质量分数。Fox方程是预测均质聚合物共混物的玻璃化转变温度的已建立方法。均质的共混物将表现出单一的玻璃化转变温度和与所述方程预测的相似的玻璃化转变温度。非均相或不相容的共混物将表现出与由Fox方程预测的玻璃化转变温度的较大偏差和/或每个组分表现出单独的转变。本领域技术人员将熟悉通过实验测量玻璃化转变温度和通过Fox方程确定玻璃化转变温度的方法。

从实例3和6以及对比实例1和9中描述的配制品制备医用粘合剂条和贴片。使用先前描述的混合程序制备材料的溶液。使用迈拉棒和305μm(12密耳)厚的垫片,将溶液涂覆到50μm厚的聚酯(迈拉)片材上。将湿涂层在烘箱中在130℃下热处理4min。使用15kg的辊将金刚石压花的低密度聚乙烯(LDPE)释放衬垫施加到干燥涂层的表面。将样品切成2.5cm的条并使其在环境条件下静置24小时。使用带有TA-243附件的TA-XT Plus型质构仪进行粘合和释放测试,以评估释放和粘附力(以N(牛顿)为单位)。释放测试在180°的角度、130mm的距离和10mm/s的速度下完成,以测量从粘合剂上去除释放衬垫所需的力。之后,将粘合剂条粘贴到聚碳酸酯(PC)上并用5kg辊压制,并且使其停留30min以准备粘附性测试。使用与释放测试所采用的相同的测试装置对PC进行粘附性测试。将样品进行三次重复测试并报告平均力(N)。

通过将有机盐和导电添加剂以不同浓度掺入实例6中描述的配制品中来制备医用电极(表8)。苄基三丁基溴化铵和乙炔黑购自西格玛奥德里奇公司。单壁碳纳米管作为Tuball 201从OCSiAl公司获得。使用针对溶液制备所述的混合程序制备具有添加剂的配制品。使用迈拉棒和2密尔厚的垫片将溶液涂覆到铝箔上。将湿涂层在烘箱中在130℃下热处理4min。使用3.5cm直径的钢模具从涂覆的铝片材上冲压出圆形电极。通过将电极粘合剂面朝下放置在第二铝片材上以形成夹层结构来制造用于电性能评估的样品。使用根据ANSI/AAMI EC12-2000的设置在单电极配置中测量电阻抗。使用GAG-810音频发生器和B&K2540B-GEN示波器在10Hz和100μA的设置下测量电极。还从配制品中制造了贴片和条,以确定粘附力和释放力。制备和测试与先前描述的实例所采用的一致。

测量成膜组合物的玻璃化转变温度并与Fox方程进行比较。对包括聚乙烯吡咯烷酮和4-2737的共混物进行了评估,并且结果如图1所示。测得的玻璃化转变温度与Fox方程预测的相似。观察到实验玻璃化转变温度与预测的玻璃化转变温度之间的一些细微偏差。这些偏差可归因于聚合物与硅酮流体之间的氢键相互作用,这影响了共混物的协同性。在文献中已经观察到由于氢键相互作用导致的玻璃化转变温度的类似偏差。成膜组合物对聚碳酸酯的剥离力(对聚碳酸酯的粘附力以实例45-48中描述的相同方法评估)表明,存在显示压敏粘附性的窄范围的组合物。图2显示了从测量图1的样品获得的差示扫描量热法热流曲线。观察到这些样品的单一玻璃化转变温度,表明实现了均质的共混物。图3和图4分别包含来自本发明的其他实施例的聚己内酯和4-7042以及聚乙烯吡咯烷酮和Dowsil 4-7042的共混物的玻璃化转变温度和粘附性结果。这些图类似地表明实现了均质的共混物,并且粘附性取决于共混物的组成。图4中的膜在测量前已从混合物中去除溶剂。图4中的最高剥离力样品对应于实例5。
上述值中的一个或多个可以变化±5%、±10%、±15%、±20%、±25%等,只要变化保持在本公开的范围内。独立于所有其他成员的马库什组的每个成员可能获得意想不到的结果。每个成员可以单独地和或组合地依赖,并且为所附权利要求范围内的具体实施例提供足够的支持。独立权利要求和从属权利要求的所有组合的主题,无论是单个还是多个从属权利要求,在此都是明确预期的。本公开是说明性的,包括描述性而非限制性的词语。根据上述教导,本公开的许多修改和变化是可能的,并且本公开可以以不同于在此具体描述的方式实施。
