Thermal Conductivity Measurements of Thermal conductivity of silk fibroin fibers by 3ω-method (CAT#: STEM-PPA-0045-WXH)

Introduction

Silk fibroin (SF) is composed by glycine, alanine, and serine in different percentages. SF fibers are obtained from diverse sources such as non- and mulberry silkworm Bombyx mori, insects, and spiders.<br />Silk fibroin can form porous 3D structures, namely sponges, foams, or scaffolds, which could be used for biomedical applications, such as tissue engineering, implantable devices, and disease models.




Principle

The process involves a metal heater applied to the sample that is heated periodically. The temperature oscillations thus produced are then measured. The thermal conductivity and thermal diffusivity of the sample can be determined from their frequency dependence.

Applications

Determining the thermal conductivities of bulk material (i.e. solid or liquid) and thin layers

Procedure

1. Sample preparation and mounting
2. Experimental condition setting
3. Experiment start: Turn on the 3ω signal generator and lock-in amplifier, and control the temperature controller to make the sample temperature reach the set value. When the sample reaches a stable state, data acquisition and processing begin.
4. Data processing
