Elastomer always exhibited poor efficiency for toughening flame-retardant polymer. In intumescent flame-retardant HDPE, a novel multi-steps processing method was employed by Chang Lu and colleagues, to fabricate a partial wetting structure in which LLDPE-g-MAH phase with the sphere was dispersed at the interface. The partial wetting structure caused a remarkable improvement of the toughness of flame-retardant HDPE with 2 wt% LLDPE-g-MAH. Its elongation at break and notched impact strength were 43% and 270% higher, respectively, than that of neat HDPE. The unique interface failure mode should be responsible for the high impact strength. DOI: 10.1002/app.48735

Immobilization of polyvinyl alcohol-siloxane on the oxygen plasma-modified polyurethane-carbon nanotube composite matrix

Electrospun polyurethane-carbon nanotube composite scaffolds were modified using oxygen plasma generator. Then, polyvinyl alcohol and polyvinyl alcohol-siloxan were immobilized on the modified surface of fibers in order to improvement of water-fiber interactions, biomineralization potential, cellular adhesion and proliferation, and osteogenic expression for efficient bone reconstruction.

Microencapsulation of oil soluble polyaspartic acid ester and isophorone diisocyanate and their application in self-healing anticorrosive epoxy resin

Microencapsulation of oil soluble polyaspartic acid ester and isophorone diisocyanate and their application in self-healing anticorrosive epoxy resin

In this study, IPDI and PAE are microencapsulated, respectively, to realize self-healing in epoxy matrix. First, IPDI microcapsules with different core/shell ratios, emulsifier dosages, and emulsification rates are prepared. Besides, during the microencapsulation of PAE, urea, tung oil, as well as aqueous isocyanate are proposed to improve the emulsion stability. Further, IPDI-PAE dual microcapsules are incorporated into epoxy coatings, and the self-healing and anti-corrosion performance are investigated systematically.
