研究目的
To investigate the relative dependency of measured colorimetric data on the temperature variation of an object for different types of colored materials.
研究成果
The study found that all samples exhibit a certain degree of change in measured color in relation to temperature change, with ceramic tiles, plastic plaques, ink-printed cards, and paint-coated samples showing a more linear trend. Textile samples performed differently, exhibiting a less linear behavior. The physical properties and chemical compositions of colorants and materials contribute to their thermochromic behavior, indicating a need for further investigation.
研究不足
The study was limited to a specific range of materials and colors, focusing on those sensitive to temperature changes. The experimental conditions were controlled, but real-world applications may present more variable conditions.
1：Experimental Design and Method Selection:
The study utilized a variety of colored samples including textile fabrics, ceramic tiles, plastic plaques, ink-printed paper cards, and paint-coated cards. The colorimetric properties of these samples were measured using a reflectance spectrophotometer with specific configurations.
2：Sample Selection and Data Sources:
Samples were selected based on their flat surface and near opacity. The temperature of each sample was measured using an infrared non-contact temperature indicator.
3：List of Experimental Equipment and Materials:
A reflectance spectrophotometer (Color i5; SN: I52671, X-rite Inc.), a conditioning chamber (SN: 11000745, SDL), and an infrared non-contact temperature indicator were used.
4：Experimental Procedures and Operational Workflow:
Samples were heated to ~60°C, and their temperature was measured before immediately measuring their colorimetric data. This process was repeated across a controlled temperature range.
5：Data Analysis Methods:
The CMC and CIEDE2000 equations were used to calculate color differences, with all calculations based on D65 illuminant and 10° observer.
