متن کاملFabrication of functionally graded bulk materials of organic polymer blends by uniaxial thermal gradient
Compositionally graded bulk materials of organic polymer blends were prepared by using nonequilibrium self-organization processes with a uniaxial thermal gradient (Bridgman method). The Bridgman method was firstly applied to prepare two kinds of polymeric compositionally graded materials: a polymer/low molecular weight additive system (poly(e-caprolactone) (PCL)/ 4,49-thiodiphenol (TDP)) and a ...
