The internal heating of the conductive channels allows a better heat transfer between fluids.
Bamboo is an abundant and low-cost material.
Bamboo is a renewable and biodegradable material.
Bamboo’s conductive microchannels allow fluids to be heated more efficiently, which is essential for microfluidic applications.
The scarcity of natural resources and the growing concern for the environment have driven the development of sustainable materials. However, many sustainable materials, such as bamboo, have low thermal and electrical conductivity, which limits their applications.
The present invention consists of a process for depositing colloidal metallic paint on the inner walls of bamboo channels. This creates hollow conductive channels that can be used to heat fluids by passing electric current through them.
The process of depositing the colloidal metallic ink takes place at room temperature. The paint is injected into the bamboo channels under pressure, and the metal particles are deposited on the channel walls. The process is simple and quick, and can be carried out on an industrial scale.
