Study on the fouling behavior of HDPE/PE-g-MA/EVA blend membrane fabricated via thermally induced phase separation method

Preparation and characterization of polyethylene/ glass fiber composite membrane prepared via thermally induced phase separation method

Grinded glass fiber (GGF) embedded high density polyethylene (HDPE) membranes were prepared via thermally induced phase separation method. FESEM images showed that all the membranes had leafy structure, indicating a solid-liquid mechanism during phase separation. The results of EDX and TGA analyses confirmed that the fibers were dispersed in the HDPE matrix uniformly. Normalized water flux of t...

Central composite experimental design applied to fabrication of LLDPE microporous membrane via thermally induced phase separation (TIPS) method

Fabrication of Gelatin Scaffolds Using Thermally Induced Phase Separation Technique

Gelatin is considered as a partially degraded product of collagen and it is a biodegradable polymer which can be used to produce scaffolds for tissue engineering. Three-dimensional, porous gelatin scaffolds were fabricated by thermally induced phase separation and freeze-drying method. Their porous structure and pore size were characterized by scanning electron microscopy. Scaffolds with differ...

Controlled release of plasmid DNA from biodegradable scaffolds fabricated using a thermally-induced phase-separation method.

Highly porous poly(D,L-lactic-co-glycolic acid) (PLGA) scaffolds were fabricated by a thermally-induced phase-separation (TIPS) method to deliver plasmid DNA in a controlled manner. A variety of TIPS parameters directly affecting pore structures and their interconnectivities of the scaffold, such as polymer concentration, solvent/non-solvent ratio, quenching methods and annealing time, were sys...

co2/ch4 separation via polymeric blend membrane

co2/ch4 gas separation is a very important applicatable process in upgrading the natural gas and landfil gas recovery. in this work, to investigate the membrane separation process performance, the gas permeation results andco2/ch4 separation characteristics of different prepared membranes (via blending different molecular weights of polyethylene glycol (peg) as a modifier with acrylonitrile-but...

Solidification Behavior of Polymer Solution during Membrane Preparation by Thermally Induced Phase Separation

The solidification behavior of poly(vinylidene fluoride) (PVDF) solution during membrane preparation by thermally induced phase separation (TIPS) was investigated. Apparatus newly developed in our laboratory was used to quantitatively measure membrane stiffness during phase separation. In this apparatus, a cooling polymer solution, placed on a stage, is moved upwards and the surface of the poly...
