Abstract: Polishing articles and methods of manufacturing polishing articles used in polishing processes and cleaning processes are provided. More particularly, implementations disclosed herein relate to composite polishing articles having tunable properties such as hydrophilicity and zeta potential. 3D printed chemical-mechanical planarization (CMP) pads composed of UV curable acrylic chemistry are generally hydrophobic in nature. Such hydrophobic behavior affects the wetting properties with abrasive-based polishing slurries such as ceria-base slurries. However, in order to increase the planarization and removal rate while decreasing defects, hydrophilic pads are preferred. In addition, it is desirable that the zeta potential (Zp) of the pads be tunable over a wide range of conditions at different pH values. Implementations of the present disclosure include methods for increasing the hydrophilicity and tuning the Zp of the pads with anionic additives and pads produced using these methods.

Abstract: The present invention generally relates to covalent network polymers prepared from an imine-linked oligomer and an independent crosslinker comprising reactive moieties selected from the group consisting of epoxy, isocyanate, bismaleimide, sulfide, polyurethane, anhydride, polyester and combinations thereof.

Further, the disclosed covalent network polymers can be formed in continuous processes, such as additive manufacturing processes that produce three-dimensional objects or roll-to-roll processes that produce covalent network polymer films or fully cured prepreg in various size formats.

Abstract: A system and method that generate marketing intelligence by auditing the effectiveness of different segments of a cross platform marketing device. The system and method allow for coordinated media for marketing purposes. The coordinated media can include graphical displays, textual displays, and various pockets holding marketing materials with embedded smart tags or smart labels. The displays can cyclically change what products or offers are displayed. Each displayed product can be linked to one or more of the materials in specific pockets. In this manner, when a product or offer is shown and a predetermined number of marketing materials are taken from the specific pocket, marketing intelligence is generated as to the effectiveness of the display and the marketing materials based partially on the smart tags or labels. The marketing materials can be a coupon or voucher.
