Abstract

本发明描述了一种方法，施用纳米尺寸二氧化钛悬浮液使得钛表面具有抗菌特性。

Description

二氧化钛纳米颗粒功能化钛金属表面的方法及功能化产品
技术领域：
本发明涉及钛金属表面处理。 
背景技术：
最近钛被广泛应用于制备用于种植学(特别是口腔正畸领域)的部件。基于这种应用，种植体各组成部件表面的杀菌和/或抑菌性能就非常重要。 
意大利专利申请FI2004A000252(以本申请人的名义)描述了一种制备二氧化钛纳米颗粒的工艺，以及该工艺所得的相关分散液，其包括将二氧化钛纳米颗粒分散在水和适当络合溶剂(例如聚乙二醇)的混合溶剂中。前述专利申请还提到了所述悬浮液可用于制备光催化涂层。 
类似的，意大利专利FI2006A000030描述了水分散液中制备二氧化钛纳米颗粒和相应分散液的方法。 
发明内容：
本发明涉及用二氧化钛纳米颗粒功能化钛金属表面的工艺，其中： 
-将被功能化的物品被浸没在二氧化钛纳米颗粒悬浮液中； 
-物品完全湿润后加热以去除溶剂； 
-物品被热循环以便改善纳米颗粒在被处理表面上的固定。 
具体实施方式：
惊讶地发现，前述专利申请所描述的二氧化钛纳米颗粒分散液可以用来处理钛表面使其可以实现杀菌或抑菌作用，而这对于由这种金属制成的假体或其部件(特别是正畸部件)非常有用。 
专利申请FI2004A000252中更详细示范的制备锐钛矿型TiO2颗粒分散液的方法可用于本发明，包括以下步骤： 
i)钛醇盐与适当络合溶剂反应； 
ii)蒸馏步骤i)所得溶剂，直到小量产物； 
iii)向步骤ii)所得溶液中添加水以及所述络合溶剂以及一个或多个缩聚抑制剂，然后回流加热反应混合物得到所需纳米颗粒分散液。 
钛醇盐优选为甲醇钛、乙醇钛、正丙醇钛、异丙醇钛、正丁醇钛、异丁醇钛，优选为异丙醇钛。 
络合溶剂优选为聚乙二醇，其分子量为例如200-600。分子量达10,000的长链聚乙二醇也可使用，二甘醇为优选。 
术语“缩聚抑制剂”是指混合物，其包括至少一个无机酸和一个有机酸，其中无机酸选自例如盐酸、硝酸、硫酸、高氯酸、氢溴酸和碘化氢，有机酸优选为乙酸；缩聚抑制剂优选为盐酸和乙酸混合物。 
缩聚抑制剂的量为：无机酸量为反应混合物总体积的0.1-10％，有机酸的量为反应混合物总体积1-20％。 
前述专利申请FI2006A000030也用来示范和要求在水中制备锐钛矿型TiO2颗粒分散液的工艺。 
基于这个方法，钛盐在水中在加热以及存在无机酸和非离子表面活性剂条件下反应，所得溶液被缩减到一个小量。专利申请FI2004A00025工艺中所述的普通和优选钛盐和无机酸都有效，但是“非离子表面活性剂”是指具有醚或酯类极性官能团的，优选为曲拉通X-100(TX-100)。 
钛醇盐与酸的摩尔比为0.005-15，优选为5-6，反应温度一般在15-95℃，优选45-55℃，反应时间为12-72小时，优选24小时。 
所述的两个申请都包括Ti可通过向步骤i)或iii)中添加金属盐而掺杂选自过渡金属的金属，特别是。以这种方法使得所形成的掺杂有Ag、Cu和Ce的TiO2分散液可以在没有紫外线照射下具有催化活性。 
下述的制备用于本发明的悬浮液的示例中，包括在络合剂中以及水性悬浮液中(示例在前述专利申请中已经给出)。 
示例
从异丙醇钛起始在水/二甘醇中制备锐钛矿型TiO 2 纳米颗粒分散液
例1
5.53L二甘醇被加入到一个20L烧瓶中，其中添加有5.54L异丙醇钛.反应混合物搅拌5分钟，然后加热到120℃蒸馏除去所形成的异丙醇，直到得到少量产品。11.1L二甘醇，、125ml的32-33％盐酸(w/w)、2.07L冰醋酸和125ml去离子水被加入；温度抬升到180℃，混合物回流2小时。 
例2
5g浓HCl、75g TX-100，加水到750g，整体置于一个2L反应器中，通过外套油循环热透加热。温度抬升到50℃。50g的Ti[OCH(CH3)2]4(TIP)被迅速加入，迅速形成白色大量凝絮沉淀。 
7小时后得到非常稳定透明溶胶。 
这样所得的悬浮液然后用于功能化钛金属部件表面。 
将被功能化的物品被浸没在悬浮液中，旋转以使其表面完全湿润。然后加热，最后进行热循环以改善纳米颗粒在被处理表面上的固定。 
用于初始浴的悬浮液通常含有0.1％-15％(优选1％)的纳米二氧化钛，0.005％-0.5％(优选0.05％)的银，所用浓度以在溶液中重量计。初始加热的单一功能是加速移除溶剂，并且优选在大约120℃的烤炉中进行。 
随后热循环包括从环境温度以温度梯度0.1-10℃/分钟提升到400-850℃，然后保持在这个温度30-240分钟，被处理的物品自然冷却到室温。 
本发明的工艺可以应用于基础表面，但是优选表面可以根据现有工艺根据其用途在浸没在二氧化钛悬浮液前进行腐蚀浸蚀。 
下面描述的基于本发明的一些例子用于处理钛物品具有杀菌特性。
