DuPont™ Kapton® Type HN Film: Kapton® Type HN film is a tough, aromatic polyimide film, exhibiting an excellent balance of physical, chemical, and electrical properties over a wide temperature range. Adhesive: Specialty / Other. These applications include, but are not limited to. Analysis of PI properties on curing temperature. In this work, microwave oxygen plasma, reactive ion etching oxygen plasma, combination of KOH and HCl solutions, and polyethylenimine solution were used as surface. Plastic films made of polyimide (PI) Kapton® high-temperature films for extreme requirements. 6%, the composite achieved outstanding. These sheets were ultrasonically cleaned sequentially with absolute ethanol and deionized water and then thoroughly dried. This is achieved by. Semantic Scholar extracted view of "Surface modifications of Kapton and cured polyimide films by ArF excimer laser: applications to imagewise wetting and metallization" by H. After electron beam was terminated, materials were exposed to vacuum environment. Several advantages of encapsulation of the crack sensor—thermal resistance, water/saline solution resistance, and durability—were verified by experiments. 3. Depending on the spacecraft orbit, it is necessary to. For applications where extremes of heat and vibration are the norm. lower than the water absorption value for the PI film.
