Thermochromic biofilm from longkong peels for temperature sensors
The biofilm from longkong peels was fabricated. Thermochromic pigments were added to biofilms. The FITR spectra confirmed all biofilms. The films responded to different temperatures. The R-biofilm changed from color to transparent at ∼35 °C to 42 °C. The RB-biofilm and B-biofilm changed from color to transparent ∼37 °C to 42 °C. All films were soluble in water. The result here promoted the potential for agricultural waste usage in temperature response. • The cellulose-based biofilm is produced from longkong peels. • Thermochromic pigment is added to biofilms. • Thermochromic-added biofilms respond to temperature change. • Thermochromic-added biofilms are soluble in water. • Thermochromic-added biofilms could be temperature sensors.
