Resin synthesis: Phenol, cashew phenol, thiab formaldehyde yog siv los ua raw khoom thiab polymerized ntawm 95-100℃rau 40-60 feeb, nrog triethylamine ua catalyst.
Cov txheej txheem hloov kho boron: 3-hydroxybenzeneboronic acid yog ntxiv rau co-condensation, thiab cov khoom siv boron-doped resin (cov ntsiab lus carbon 89.3%) tau txais tom qab carbonization.
Ester curing txheej txheem: Qhov zoo tshaj plaws curing tus neeg saib xyuas ntau npaum li cas yog 25%, cov tshuaj resin yog 1.5-2.0%, thiab thermal decomposition pib kub txog 310 degree.
