Preparation and Properties of CA/γ-Poly(glutamic acid)/ZnO Electrospun Membranes.

ABSTRACT

Cellulose acetate (CA) fibrous membranes blended with poly-(γ-glutamic acid) (γ-PGA) and ZnO were produced via electrospinning. The performance of the obtained composite membrane was investigated by scanning electron microscopy (SEM), Fourier transform IR spectroscopy, tensile test, water contact angle, and thermogravimetric analysis. The corn plant height, leaf area and SPAD (soil and plant analyzer development) were compared with plants covered with CA/γ-PGA and CA/γ-PGA/ZnO fibrous membranes at room temperature. Simultaneously, the water absorption and degradation rate were also studied. The results obtained indicate the potential use of these fibrous membranes for mulching film applications. The fibrous membranes could also find potential use as a material for food packing, facial mask and as antimicrobial films for wound dressing.
