Texture Induced by Molecular Weight Dispersity: Polymorphism within Poly(L-lactic acid) Spherulites被引量:1
《Chinese Journal of Polymer Science》2020年第12期1365-1373,共9页Da-Peng Hu Min Chen Yu-Hui Yang Han-Ying Li 
supported by the National Natural Science Foundation of China(Nos.51625304 and 51873182).
Poly(L-lactic acid)(PLLA)has drawn much attention due to its excellent medical and pharmaceutical applications for decades.As a semi-crystalline polymer,morphology and crystal structure of PLLA greatly determine its p...

ISOTHERMAL CRYSTALLIZATION BEHAVIOR AND UNIQUE BANDED SPHERULITES OF HYDROXYAPATITE/POLY(L-LACTIDE) NANOCOMPOSITES被引量:2
《Chinese Journal of Polymer Science》2010年第4期499-507,共9页陈学思 
supported by the National Natural Science Foundation of China(Key Project No.50733003 and Project No.20604030);the International Cooperation fund of Science and Technology(Key project 20071314) from the Ministry of Science and Technology of China;the fund from Chinese Academy of Sciences(KGCX-YW-208)
Hydroxyapatite/poly(L-lactide) (HA/PLLA) nanocomposites were prepared by the solvent mixing method. The isothermal crystallization behavior was studied by differential scanning calorimetry (DSC) and polarized op...
