چکیده
|
A series of poly(l-lactic acid)/poly(tetramethylene glycol) (plla/ptmg) blend films were prepared by casting the polymer blend solution in chloroform. surface morphologies of the plla/ptmg blend films were investigated by scanning electron microscopy (sem). thermal,mechanical,and chemical properties of plla/ptmg blend films were studied by differential scanning calorimetry (dsc),thermogravimetric analysis (tga),tensile tests,and surface contact angle tests. it was revealed that the introduction of flexible ptmg could markedly modify the properties of the plla films.
