Polymer, branched Deposition

From the observations on branched PEO and alkanes more general conclusions can be drawn about the overcrowding problem at the crystalline—amorphous interface in polymers and about the mechanism of chain deposition during crystal growth. Thus, e.g., although for the Y-shaped alkane the energeti-... 

On the solvent-treated silicon surface, the polymeric coating is deposited selectively. Adsorption and nucleation of polymeric microparticles on the silicon surface are nonuniform. These polymer films contain cross-links with the relative high length of the molecular branches. 

In a more fundamental perspective the concept of confining catalytically active salts on supports may be regarded as a branch of the common concept of supported liquid phase (SLP) catalysts, where a non- or low-volatile catalyst solution of, for example, pyrosulfates [26], hydrophilic polymer glycols [27-29], phthalates [22] or water (i.e. supported aqueous phase, SAP) [30-33] are deposited on a high-surface area porous support. 

The use of polymeric ammonium salts and a sulfonic acid salt of sodium is an easy and efficient way of coating fabrics furthermore, employing the layer-by-layer (LbL) deposition technique can broaden the application of N-halamine biocides in other polar substances for use as antimicrobial coatings. Branched PEI, polypropylene (PP) and styrene maleic anhydride copolymers are a very good coating for food packaging materials, possibly due to the presence of both cationic- and N-halamine-forming structures. N-halamine cationic antimicrobial polymers based on (acrylamidopropyl)trimethylammonium chloride, PDDA chloride and poly(2-acrylamido-2-methylpropane sulfonic acid sodium salt) have been synthesised and coated onto cotton fabrics via an LbL deposition technique. 

Chemical vapor deposition (CVD) of polymers is an elegant technique to place coatings on various substrates without using solvents. However, the equipment needed is more complicated in comparison to conventional techniques. CVD is used in various branches of industry for corrosion resistant and protective coatings.
