We report here a simple but practical method to prepare crosslinked PCL membranes by using dual pore-forming agents. Their porosities, section morphologies, melting behaviors and mechanical properties are evaluated. The results show that the membranes have a pore size close to 5µm, and the porosities are maintained 70–80%. The mechanical properties show the membranes have improved Young's modules...
Gradual precipitation method was used to generate porous PLLA materials with adjustable morphology and micropores. By adjusting the solvents and concentrations of polymer solution, we could conveniently get PLLA nano-units, which further formed porous materials with tunable porosities (91.4–97.5%). It was found that nanosheets, fibrous nanosheets, and nanofibrous networks were produced from solutions...
