Examples
Embodiment 1
[0028] Measure 2ml of CH 2 Cl 2 and 2ml of CF 3 The COOH solution was stirred evenly in the Erlenmeyer flask and used as a solvent. Weigh 0.2g of PET (Mw=18,000) chips and 0.2g of PHEB powder (Mw=23,700) and dissolve them in the above solvent, and stir magnetically at room temperature until PET and PHEB are completely dissolved. Weigh 0.02 g of titanium dioxide nanoparticles (100% anatase type, particle size ≤ 25 nm), add to the above PET / PHEB solution, and magnetically stir for 4 hours to obtain an electrospinning solution, which is ready for use.
[0029] Inject the electrospinning liquid into the glass syringe, adjust the voltage in the electrospinning conditions to 14.5KV, the spinning distance is 15cm, and the spinning speed is 0.5ml / h, and the electrospinning PET / TiO 2 / PHEB composite fiber membrane.
[0030] Scanning electron microscopy (Hitachi SU8000Series) was used to measure the microscopic morphology of the fiber membrane, and the test results were as follows: ...
Embodiment 2
[0032] Measure 2ml of CH 2 Cl 2 and 2ml of CF 3 The COOH solution was stirred evenly in the Erlenmeyer flask and used as a solvent. Weigh 0.28g of PET (Mw=18,000) chips and 0.12g of PHEB powder (Mw=23,700) and dissolve them in the above solvent, and stir magnetically at room temperature until PET and PHEB are completely dissolved. Weigh 0.02 g of titanium dioxide nanoparticles (100% anatase type, particle size ≤ 25 nm), add to the above PET / PHEB solution, and magnetically stir for 4 hours to obtain an electrospinning solution, which is ready for use.
[0033] Inject the electrospinning solution into the glass syringe, adjust the voltage in the electrospinning conditions to 14KV, the spinning distance is 12.5cm, and the spinning speed is 0.75ml / h, and the electrospun PET / TiO 2 / PHEB composite fiber membrane.
[0034] After testing, compared with Comparative Example 1, the titanium dioxide agglomeration phenomenon has been greatly improved, but not as obvious as in Example 1...
Embodiment 3
[0036] Measure 2ml of CH 2 Cl 2 and 2ml of CF 3The COOH solution was stirred evenly in the Erlenmeyer flask and used as a solvent. Weigh 0.36g of PET (Mw=18,000) sliced particles and 0.04g of PHEB powder (Mw=23,700) and dissolve them in the above solvent, and stir magnetically at room temperature until PET and PHEB are completely dissolved. Weigh 0.02 g of titanium dioxide nanoparticles (100% anatase type, particle size ≤ 25 nm), add to the above PET / PHEB solution, and magnetically stir for 4 hours to obtain an electrospinning solution, which is ready for use.
