说明

用于生物医学应用的可生物降解导电聚合物。 PCL 二醇嵌段的平均分子量为 2000,PPy 嵌段的平均分子量为 4000,掺杂水平为 25%。良好的生物相容性,在 pH=7 缓冲液中 200 天时预期重量减轻 40%。

薄膜可以通过以 1000 rpm 旋转浇铸硝基甲烷分散体来制备。通过将分散体空气喷涂在基材上,可以制备更厚且导电性更强的薄膜。喷涂后的薄膜可以在 30-40 °C 下干燥,然后在两个抛光的染料板之间以 1000-10,000 psi 的压力进行压制,以增加薄膜的密度、强度和抗划伤性。

嵌段共聚物结构使导电聚合物聚吡咯可分散在有机溶剂中并且可生物降解。

在室温下储存本产品(不要冷藏或冷冻)。通常会发生严重的沉降和分离。使用前搅拌、超声处理和过滤。移液管中的玻璃棉塞可用于轻松过滤。该产品的保质期将根据其存储和处理方式而有所不同。如果发生严重聚集,或者如果超声/过滤不足以产生良好的浇铸溶液,则应丢弃产品。使用喷涂时,用户应采取一切必要的预防措施,以防止接触本产品的溶剂蒸气

一般描述

Sheet resistance, spin cast thin films: 10,000-50,000 Ohms/sq

Average transmittance: 70-90%

Biodegradble conducting polymer for bomedical applications. PCL diol blocks have average molecular weight 2000 and PPy block have an average molecular weight of 4000 with a 25% doping level. Good biocompatibility with expected weight loss of 40% at 200 days in pH=7 buffer.
 

应用

Thin films can be prepared by spin casting the nitromethane dispersion at 1000 rpm. Thicker and more conducting films can be prepared by air spraying the dispersion on a substrate. Sprayed films can be dried at 30-40 °C, then pressed between two polished dye plates at 1000-10,000 psi to increase film density, strength and scratch resistance.
 

特点和优势

The block copolymer structure renders the conducting polymer polypyrrole dispersible in organic solvents and biodegradable.
 

注意

Store this product at room temperature (do not refrigerate or freeze). Severe settling and separation will normally occur. Agitate, sonicate, and filter prior to use. A plug of glass wool in a pipette can be used for easy filtration. The shelf life of this product will vary depending on how it is stored and handled. Product should be discarded if heavy aggregation occurs, or if sonication / filtering are inadequate to produce a good casting solution. When spray coating is used, the user should take every precaution necessarily to prevent exposure to solvent vapors from this product
 

其他说明

Will settle over time. Must be sonicated before use
