Preparation, characterization, and adsorption application of poly (lactic acid)/tea polyphenols porous composite nanofiber membranes

In this study, Poly (L-lactic acid)/Captopril composite nanofiber membranes were electrospun for drug delivery. Different mass fractions of Poly (L-lactic acid), different ratios of Captopril and the influences of PEG4000 added in the spinning solution are discussed. The morphology, chemical components, the surface areas and pore sizes, wettability of the composite nanofiber membranes were investigated. The results showed that the diameters of the composite nanofibers increased with the increase of Poly (L-lactic acid) mass fractions, the diameters decreased with the increase of Captopril content as well as the addition of the surfactant. Fourier Transform Infrared (FT-IR) showed the chemical components of Captopril remained unchanged when it was electrospun into the composite nanofibers. The surface areas pore width and pore volume of the composite nanofibers became a little larger than those of poly (L-lactic acid) nanofibers, and the wettability of the composite nanofiber membranes was better than those of poly (L-lactic acid) nanofiber membranes. Wettability was improved by an increase of the drug load amount.

Poly(lactic acid)/hexadecyl trimethyl ammonium chloride-modified montmorillonite clay nanofiber membranes have been fabricated by the electrospinning technique. The nanofiber membranes were then characterized by scanning electron microscopy and Fourier transform-infrared spectroscopy. Nanofiber membranes with different ratios of Poly(lactic acid) and hexadecyl trimethyl ammonium chloride-modified montmorillonite have been spun by varying voltage supply during electrospinning. These parameters were found to have a substantial effect on the morphologies of these membranes. It was found that 8% (w/w) Poly(lactic acid)/hexadecyl trimethyl ammonium chloride-modified montmorillonite concentration is an ideal condition to obtain thinner and uniform Poly(lactic acid) fibers. The results also suggested the coexistence of exfoliated hexadecyl trimethyl ammonium chloride-modified montmorillonite layers over the studied hexadecyl trimethyl ammonium chloride-modified montmorillonite contents. Fourier transform-infrared spectroscopy revealed that there might be possible interactions between the hexadecyl trimethyl ammonium chloride-modified montmorillonite clay and Poly(lactic acid) matrix.
