半岛bd体育手机客户端 说明

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.

包装

25 g in glass bottle

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 ℃, 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
