摘要：Interconnected porous PLA materials were prepared by mixing PLA with Sodium Chloride (NaCl) and polyoxyethylene (PEO) in a two-rotor continuous mixer. SEM, DSC and XRD were used to study the effect of PEO contents and mixing parameters on interconnected porous structure, porosity and crystallization properties. The results showed that increasing PEO content and rotor speed improved pore connectivity. Rotor speed also enhanced PLA crystallization.
