Název v původním jazyce

Parylene-C encapsulated Cu coated nonwovens for thermotherapy application

Popis výsledku v původním jazyce

Metalized textiles were recognized as effective material for thermotherapy application. However, the air permeability for most metalized textiles were poor due to the protection coating of the metal layer. This study employs Parylene-C as an encapsulating material, utilizing a specific equipment-based vapor deposition method to completely encapsulate fabrics with metal particle coatings in a Parylene-C film without covering all fabric pores and ensuring a certain level of breathability. After the encapsulation process, the thickness of the sample was increased, and the porosity was decreased. Even though the overall porosity of the fabric decreases after encapsulation with a Parylene-C coating, it retains an elegant degree of breathability, distinguishing it from traditional protective coatings where the protective film does not completely seal the fabric pores. Prior to encapsulation with Parylene-C, conductive strips with protective tape were attached to the ends of the material. After removing the protective tape post-encapsulation, applying a direct current to the conductive strips enables fabric heating through the Joule effect. This method allows the material‘s surface temperature to reach approximately 45°C with a 2V voltage application at the ends, fully meeting the temperature requirements for thermotherapy.
