PREPARATION OF POLYPHOSPHAZENE MICROPARTICLES VIA ELECTROSPRAY
静电喷雾法制备聚膦腈微球

The electrospray technique was used to prepare poly(ethylglycino)-(phenylalanine ethyl ester) phosphazene] microparticles with very low polydispersity.By replacing the chloroform atoms of polydichloro-phosphazene with alanine ethyl ester and glycine ethyl ester subsequently,poly(ethylglycino)_(0.30)(phenylalanine ethyl ester)_(0.70)phosphazene](PGPP) was obtained and electrosprayed.The effects of processing parameters such as solvent,polymer concentration,liquid flow rate,applied voltage and receiving dis...
