Case Study

How Does Ethylenediamine Tetrakis(Ethoxylate-Block-Propoxylate) Tetrol (ETT) Affect Tin Electrodeposition

Hu, Yang, et al. Electrochimica Acta, 2022, 421, 140476.

This study examined the influence of ethylenediamine tetrakis(ethoxylate-block-propoxylate) tetrol (ETT, average molecular weight 7,200), a compound consisting of four polyether block copolymers linked by an ethylenediamine moiety, on the electrodeposition of tin (Sn). Previous research has indicated that similar additives, albeit with different molecular weights, successfully facilitate the bottom-up filling of copper in silicon vias (TSVs) with extremely high aspect ratios. In this investigation, a thorough analysis was conducted to not only elucidate the suppression mechanism of ETT on Sn deposition but also to distinguish the impact of ETT's various structural components on this inhibitory effect.
Electrochemical characterization of Sn in the presence of ETT is performed through techniques such as cyclic voltammetry (CV), chronoamperometry, and chronopotentiometry. The study systematically explores several variables, including ETT concentration, rotation rate, and potential scan rate. The findings reveal that ETT inhibits Sn deposition within a specific range of negative potentials, linked to the potential-dependent adsorption of ETT on the electrode surface. This adsorption phenomenon is influenced by both the fraction of the surface that is unoccupied and the extent of surface coverage.

Copolymer Ethylenediamine Tetrakis(Ethoxylate-Block-Propoxylate) Tetrol for the Preparation of Polyurethane Poly(High Density Polyethylene)

Gui, Haoguan, et al. Chemical Engineering Journal, 2019, 365, 369-377.

A series of poly(ethylenediaminetetra(ethoxylate-block-propoxylate)tetraol) poly(PU polyHIPE) with high porosity, highly interconnected, open-cell microphase separation, and hierarchical macroporous structure were prepared by step-wise polymerization (SGP) of X-type block copolymers (ethylenediaminetetra(ethoxylate-block-propoxylate)tetraol, T1107) and isocyanate. These PU polyHIPEs are excellent candidates for the absorption and removal of toxic halogenated liquids. In this work, T1107 can be used as both a stabilizer and a monomer for non-aqueous high internal phase emulsions (HIPE).
PolyHIPEs synthesis from T1107
The resulting polyHIPEs, prepared according to specific formulations, were labeled PU-X-Y, where X (75, 80, and 83) indicates the volume percentages of the internal phase and Y (10, 20, and 30) denotes the concentration of T1107 in the continuous phase. Analogous HIPEs without polyMDI were also produced, referred to as HIPEX-Y. The preparation process for PU-80-20 is outlined below. PolyMDI and T1107, mixed in a 10:1 ratio of -NCO to -OH, were dissolved in DMSO, followed by the addition of paraffin oil to the DMSO solution while stirring with a vortex mixer. After stirring for 15 minutes, a paraffin oil-in-DMSO HIPE was generated, to which DBTDL was added, followed by an additional 5 minutes of stirring. The HIPEs underwent polymerization for 24 hours at 60 °C in a convection oven. After polymerization, the resulting monolithic polyHIPEs were cut and subjected to Soxhlet extraction first with acetone and then with ethanol, each for 24 hours, to eliminate unreacted monomers. Finally, the solvents within the PU-X-Y were removed via freeze-drying.
