Preparation of hydrophilic HDPE porous membranes via thermally induced phase separation by blending of amphiphilic PE-b-PEG copolymer

Effect of PE-g-MA compatibilizer on the structure and performance of HDPE/EVA blend membranes fabricated via TIPS method

“…PE has recently attracted much attention in membrane related reserarches; however, it suffers from some drawbacks including non-wettability, poor stress crack resistance, poor compatibility with various additives such as nanoparticles or reinforcement fillers and more importantly, fouling in micro and ultrafiltration processes, which have restricted its application (Zhang et al, 2010). When solutes or particles deposit onto membrane surface or into membrane pores, fouling occurs resulting in decline in membrane performance.…”

NOM fouling behavior during ultrafiltration: Effect of membrane hydrophilicity

“…Among these materials, PEO-like polymers have attracted much attention due to their superior antifouling ability [37]. Although the kinetic and thermodynamic reasons for the protein resistance of PEO are still controversial, many researchers have attempted to mix the various PEO-containing amphiphilic copolymers with the usually used membrane materials to prepare the antifouling membranes [10][11][12][13][14][15][16][17][18][19][20][21]. The results confirmed that PEO chain had a trend to enrich on the membrane surface, which imparted good hydrophilicity to the hydrophobic membranes.…”

“…It is generally accepted that improving the intrinsic hydrophobic character of membranes is the most common method to avoid the non-specific adsorption between membrane and solute. Several hydrophilic materials were used to enhance antifouling ability of the conventional hydrophobic membranes, including PEO-like polymers [10][11][12][13][14][15][16][17][18][19][20][21][22], zwitterionic polymer [23][24][25], phospholipid polymer [26,27], heparin [28,29], zirconium oxide [30], titanium oxide [31], zeolite [32], silica [33], carbon nanotubes [34], graphene oxide [35], and their mixture [36]. Among these materials, PEO-like polymers have attracted much attention due to their superior antifouling ability [37].…”

Role of Cured Epoxy and Block Copolymer Addition in Mechanical and Thermal Properties of Polyethylene

“…Literature points out that PEG block can react with epoxy phase [14][15][16] and PE block presents affinity with HDPE phase 17 . Zacharuk et al 14 studied epoxy nanocomposites with carbon nanotubes functionalized with poly(ethylene glycol).…”

“…Authors observed the occurrence of a reaction between epoxy groups of DGEBA (diglycidyl ether bisphenol A) and the PEG hydroxyl groups, at elevated temperatures or in the presence of a catalyst. Zhang et al 17 observed that PE block of PE-co-PEG anchored in the HDPE phase of membrane surface. In this context, the main goal of this paper is to investigate the effect of epoxy addition on the mechanical and thermal properties of HDPE.…”
