Embodiment 1
[0057] Step 1: Prepare anhydrous toluene
[0058] Toluene C 6 H 6 The sodium and Na are put into the first reaction vessel through the opening A, reflux at 110℃ (measured by the thermometer in real time) to remove trace water in toluene, and then distilled at 112℃ (measured by the thermometer in real time) Obtain anhydrous toluene; add 5g of sodium to 100ml of toluene;
[0059] Step 2: Preparation of PCS-toluene solution
[0060] Dissolve polycarbosilane (PCS) in the anhydrous toluene prepared in step 1 to form a PCS-toluene solution; add 1g of polycarbosilane to 1ml of anhydrous toluene;
[0061] Step 3: Prepare PBS-toluene solution
[0062] Dissolve polyborosilazane (PBS) in the anhydrous toluene prepared in step 1 to form a PBS-toluene solution; add 1ml of polyborosilazane (PBS) to 1ml of anhydrous toluene;
[0063] Step 4: Precursor polymer alloy
