This study reports on the effects of cyclic hot and cold water absorption on the dielectric properties of luffa–polylactide composites and their potential application as a quadratic mallet finger splint. The study was conducted for dry samples varying in fiber volume percentage from 0% to 20% with increments of 5%. The 15 vol% luffa–polylactide composites were subjected to the cyclic hot and cold water absorption. The changes in the dielectric constant, dissipation factor, and loss factor were measured in the 100 Hz to 1 MHz range. It was found that the higher the number of water cycles, lower the dielectric constant, dissipation factor, and loss factor. Cyclic hot water absorption showed a more significant effect on the dielectric properties than the cyclic cold water absorption. J. VINYL ADDIT.
