A scrubber and methods of forming a scrubber. The scrubber may include a foamed melamine resin, a first foamed polyurethane resin, a second foamed polyurethane resin, and a binder. The scrubber can be configured to exhibit the properties of both a scrubber and an eraser, and have a density ranging from 0.01 to 0.5 grams per cm.sup.3. A method of forming the scrubber may include the following steps: mixing foamed melamine resin particles, first foamed polyurethane resin particles, and second foamed polyurethane resin particles to form a first mixture; and mixing the first mixture with a binder to form a second mixture.

The disclosure provides a solvent resistant polyimide/polyethyleneimine@titanium dioxide nanohybrid ultrafiltration membrane with high solvent permeability and a preparation method thereof. The preparation method comprises the following steps: dissolving a titanium dioxide precursor Ti-BALDH and polyimide into N-methylpyrrolidone to prepare a casting solution, then coating on the non-woven fabric, and preparing the solvent resistant nanohybrid polyimide membrane in one step through a non-solvent induced phase separation-interface crosslinking-in-situ biomimetic mineralization coupling method. According to the disclosure, a solvent resistant polyimide/polyethyleneimine@TiO.sub.2 nanohybrid ultrafiltration membrane (PEIPI@TiO.sub.2) with high solvent permeability prepared through a simple non-solvent induced phase separation-interface chemical crosslinking-in-situ bionic mineralization coupling method.

This invention describes branched amino and carboxylated natural oils. The chemistries are derived from plant-based epoxidized oils, alkanol amines, citric acid, and choline chloride. The process described has 100% atom efficiency and no waste.

A population of nanocomposite particles including nanoparticles and poly (ethylene imine) (PEI) grafted thereto. In some embodiments there is no intervening layer between the nanoparticles and the PEI. Methods of making and using nanocomposite particles are also disclosed.

The present disclosure discloses a rubber filler, a rubber composite including the same, a preparation method therefor, and use thereof. The rubber filler includes polydivinylbenzene microspheres and polydopamine-modified white carbon black loaded on the polydivinylbenzene microspheres; wherein the mass ratio of the polydivinylbenzene microspheres to the polydopamine-modified white carbon black is 1:(0.5-20). The rubber composite includes: a solution polymerized crude rubber and the rubber filler; wherein the rubber filler is added in an amount of 10-60 wt % of the dry basis mass of the solution polymerized crude rubber. The present disclosure uses polydivinylbenzene microspheres loaded with polydopamine-modified white carbon black as the filler, solving the problem that the white carbon black is apt to agglomerate and the white carbon black has poor binding force with the rubber. The rubber composite obtained by the present disclosure is suitable for manufacturing green tires.
