Embodiment 1
[0026] Embodiment 1: The preparation method of bio-based light-to-heat conversion material in this embodiment is carried out according to the following steps:
[0027] Step 1. Put the inner skin of pomelo peel into absolute ethanol, ultrasonically treat it at a frequency of 40KHz for 30 minutes, take it out, then wash it repeatedly with deionized water until the ethanol is completely removed, and then dry it in an oven at 80°C for 20 hours;
[0028] Step 2. After uniformly mixing 20mL of acetone and 20mL of absolute ethanol, add 10g of E51 type epoxy resin, 2.5g of alkylaryl polyether alcohol and 5g of carbon black, and disperse with 1400rpm high-speed sand mill for 5 hours to obtain a uniform dispersion;
[0029] Among them, E51 epoxy resin was purchased from Sinopharm Chemical Reagent Co., Ltd., alkylaryl polyether alcohol was purchased from Guangzhou Desong Chemical Co., Ltd., model 405, and carbon black was purchased from Sinopharm Chemical Reagent Co., Ltd.
