Cationic waterborne polyurethane as a new dispersing polymer was synthesized by using relatively hydrophilic polyols. Dispersing cationic polyurethane (DCPU) nanocomposites were prepared using isophorone diisocyanate (IPDI), polyethylene glycol (PEG) with different molecular weights (Mn=200, 400, 600,and1000 g/mol), N-methyl diethanolamine (MDEA), dibutyltin dilaurate (DBTDL) and different perc...
Chemical mechanical polishing (CMP) is a key step in semiconductor technology because it crucial to produce defect-free and flat enough surface for further processing of microelectronic devices. Silicon (Si) wafer widely used integrated circuit (IC) devices, high-density information storage other advanced applications. In this paper, the effect different pH three ethanolamines, such as monoetha...
OBJECTIVES The purpose of this research was to develop a simultaneous determination method for monoethanol-amine (MEA) and diethanolamine (DEA) in workplace air for risk assessment. METHODS The characteristics of the proposed method, such as recovery, quantitation limit, reproducibility and storage stability of the samples, were examined. RESULTS An air sampling cassette containing two sulf...
The shuttle effect of soluble lithium polysulfides (LPS), which causes rapid capacity fading, remains a lingering issue for lithium-sulfur batteries (LSBs). Herein, we report new type reactive molecule-based LPS trapper, zinc acetate-diethanolamine (Zn(OAc)2·DEA), demonstrates molecular efficiency 1.8 trapping, approaching its theoretical limit 2, is the highest trapping capability reported so ...
