چکیده

To develop more green polymer composites and further know the performance of green composites, the composites based on green poly(L-lactic acid) (PLLA) and starch were fabricated by a counter-rotating mixer. And effect of starch on the fluidity and nucleating performance of PLLA was investigated using melt index instrument, optical depolarizer and wide angle X-ray diffraction instrument, respectively.

Preparation and Characterization of Poly(Lactic Acid)-g-Maleic Anhydride[thinsp]+[thinsp]Starch Blends

Poly(lactic acid) (PLA) and starch copolymers are obtained by reactive blending varying the starch compositions from 0 to 60%. PLA is functionalized with maleic anhydride (MA), obtaining PLA-g-MA copolymers using dicumyl peroxide as an initiator of grafting in order to improve the compatibility and interfacial adhesion between the constituents. PLAþ starch blends without a compatibilizer do not...

Preparation of antibacterial electrospun Poly lactic-co–glycolic acid nanofibers containing Hypericum Perforatum with bedsore healing property and evaluation of its drug release performance

Skin drug delivery systems with controlled release are suitable means for the local transfer of pharmaceutical compounds to the damaged and healthy layers of skin. Nanofibrous membrane prepares uniform moisture in the wound environment with less accumulation of fluid secretion due to its variable pore size. Electrospinning takes advantage of using herbal extracts in the form of electrospun nano...
