Researchers from Department of Chemistry Describe Findings in Applied Polymer Science (Phase Separation to Create Hydrophilic Yet Non-Water Soluble PLA/PLA-b-PEG Fibers via Electrospinning)

By a News Reporter-Staff News Editor at Journal of Technology -- A new study on Applied Polymer Science is now available. According to news reporting out of South Hadley, Massachusetts, by VerticalNews editors, research stated, "In moisture wicking fabrics, fibers with hydrophilic surfaces that are also non-water soluble are desirable. In poly(lactic acid), PLA, fibers it is expected that the addition of poly(ethylene glycol), PEG, will monotonically increase their wicking rates."

Our news journalists obtained a quote from the research from the Department of Chemistry, "In this paper, phase separation was used to create biocompatible, biodegradable, hydrophilic yet non-water soluble fibers by electrospinning PLA with PEG and PLA-b-PEG copolymers. By tuning the thermoelectric parameters of the apparatus, and the chemical properties of the dopes, the amount of PEG in the fibers was improved over prior work; concentration increased by 60% (by weight, wt %) to 16 wt % in the PLA fiber. Instead of the expected increasing wicking rates with PEG concentration, there is a peak at 12 wt %; at greater concentrations, wicking decreases due to PEG crystallization within the PLA (verified via DSC)."

According to the news editors, the research concluded: "At 12 wt % PEG from copolymers, the nanofabric's wettability increases to 1300% its original weight."
