Title:
TEMPERATURE-CHANGE SENSING SUBSTRATE COMPRISING SELF-HEALING POLYURETHANE POLYMER
Document Type and Number:
WIPO Patent Application WO/2021/096215
Kind Code:
A1
Abstract:
The present invention relates to a temperature-change sensing substrate comprising a self-healing polyurethane polymer. More specifically, the present invention relates to a temperature-change sensing substrate having a self-healing polyurethane polymer matrix and a plurality of pores dispersed in the matrix. The temperature-change sensing substrate according to the present invention can be applied as a temperature-change sensor for preventing the spoiling of refrigerated or frozen food and medical supplies. For example, substrate, which was opaque when stored at -60°C, -50°C, -30°C, -20°C, -10°C and the like, becomes transparent if the temperature rises to 0°C, 10°C, 20°C, 30°C and the like, and thus a temperature-change sensor capable of checking storage conditions through a change in light transmittance can be provided.
