Process for preparing a colourless solution of 3-(N-benzyl-2-aminoethyl)aminopropyltrimethoxy-silane hydrochloride in methanol
A process can prepare a colourless, methanolic solution of 3-(N-benzyl-2-aminoethyl)aminopropyltrimethoxysilane hydrochloride. The process includes, in step 1 fractionally distilling the vinylbenzyl chloride reactant component with addition of at least one stabilizer, and in step 2, metering and mixing the distillate (vinylbenzyl chloride) from step 1 into an initial charge of N-(2-aminoethyl)-3-aminopropyltrimethoxysilane and methanol in a molar ratio of the N-(2-aminoethyl)-3-aminopropyltrimethoxysilane to vinylbenzyl chloride of 1.0:0.80 to 1.0:1.15 and at a temperature in the range from 40 to 60 C. and leaving them to react further. The colourless, methanolic solution has an APHA colour number of <200 mg PtCo/I.
SOFT MATERIAL, METHOD FOR ELECTROSTATICALLY INDUCING DEFORMATION THEREIN, AND SOFT ROBOT
A soft material comprises a film and a gel system covered by the film. The film is made of polydimethylsiloxane, polytetrafluoroethylene, polymethyl methacrylate, polyxylene, polystyrene, rubber or nylon. The gel system comprises a gel and saline solution. The gel is a polymer network structure, and the saline solution is infilled in interspaces of the polymer network structure. The film is electrostatically neutral, and the soft material has an original electrostatic equilibrium state. When the original electrostatic equilibrium state is broken by electrostatic induction (such as being rubbed by a human hand), the gel expands or shrinks. The disclosure also provides a method for auto-deforming the soft material and a soft robot using the soft material.
Aqueous resin based inkjet inks
An inkjet ink includes a) an aqueous medium; and b) capsules composed of a polymeric shell surrounding a core; wherein the capsules are dispersed in the aqueous medium using a dispersing group covalently bonded to the polymeric shell; wherein the core contains a photoinitiator and one or more chemical reactants capable of forming a reaction product upon application of UV light; wherein the capsules have an average particle size of no more than 4 m as determined by dynamic laser diffraction; and wherein the photoinitiator is a diffusion hindered photoinitiator selected from the group consisting of multifunctional photoinitiators, oligomeric photoinitiators, polymeric photoinitiators and polymerizable photoinitiators.
Use of gel beads to control droplet dispersion
A method of generating deformable gel beads that contain a single colloidal particle is described. Gel beads containing a particle are isolated from those that do not contain a particle, based on differences between the buoyant density of these gel bead populations. The gel beads containing a particle are subsequently co-encapsulated at a high efficiency into droplets that can comprise additional objects such as cells, other particles, or reagents. The gel coating on the rigid particle prevents clogging in narrow channels, such as those of a droplet generator.
