“…The surface is then dried to remove the solution, leaving behind BP . The all-dry method exposes the to-be-grafted surface to BP vapor, and the surface uptakes BP during the exposure. − Although different, these three categories use the same type II behavior of BP under UV irradiation, resulting in abstraction of labile hydrogen atoms from the surface to create chain-initiating radicals.…”

“…The envisioned scheme combines the benefits of iCVD and grafting by exposing surfaces to vapors of a type II photoinitiator, BP. All-dry vapor-phase photografting has been demonstrated, − but lacks characterization for key features such as molecular weight and graft density. The goal of this work is to use an existing CVD chamber to perform and extensively characterize films produced by solventless grafting, hereby referred to as grafting CVD (gCVD), onto both flat and textile polymer substrates.…”

Vapor-phase deposition and characterization of covalently bound polymer coatings using type II surface photoinitiation of the monomers (dimethylamino)methyl styrene (DMAMS) and (diethylamino)ethyl acrylate (DEAEA) are reported. Grafting chemical vapor deposition (gCVD), a solventless, low-temperature process, was first used for coating finished nylon fabric with a previously characterized antimicrobial polymer, PDMAMS. The gCVD process was then further explored using the less-UV-sensitive monomer DEAEA for deposition onto spun-cast PMMA thin films. The structure was confirmed with Fourier transform infrared (FTIR) spectroscopy. Durable films up to 54 nm thick retained 94% of their thickness after 10 rounds of ultrasonication. Optimization of conditions allowed for the deposition of soluble films. Gel permeation chromatography (GPC) and variableangle spectroscopic ellipsometry (VASE) swelling cell measurements gave an estimated graft density range of 0.06-0.25 chains/nm 2 .

“…This suggests an Hemoglobin washability of grafted nylon-6 improvement in the hydrophilic properties, which are related to the washability. On the other hand, it has been reported that KOH (Hegazy et al, 1990) or Na 2 CO 3 (Howard et al, 1969) as well as NaOH can be used in the solution of neutralization treatment after graft polymerization, and the hydrophilic property of the grafted substrate is improved remarkably by post-treatment in any case.…”

Purpose -To explore the effect of acrylic acid polymerization and NaOH treatment of nylon-6 on hemoglobin washability. Design/methodology/approach -The nylon-6 was chemically grafted with acrylic acid and treated with NaOH for the purpose to improve the washability of hemoglobin as a blood protein soil. The structural change before and after graft polymerization was analyzed by X-ray photoelectron spectroscopy and scanning electron microscopy. The moisture regain, the contact angle, and the washability were each measured. Findings -Graft polymerization and NaOH treatment of nylon-6 changed the surface energy and structure of nylon-6 causing the washability of hemoglobin to improve. Compared to ungrafted nylon-6, the hydrophilic properties were increased remarkable by graft polymerization and NaOH treatment, which reulted in the improvement of washability. Practical implications -Hemoglobin is one of the most difficult soils to remove from the fabric. The paper might be of interest to those who would consider purchasing fabrics that are good at both hydrophilic properties and washability. Originality/value -The study on washability of hemoglobin as a blood protein soil for grafted fabric has not been reported so far. The results of this research may be used in a basic research for the development of new process which is capable of improving of hemoglobin washability.

“…Here, polymer samples were irradiated in a solution containing a vinyl monomer and a photosensitizer5 or were irradiated after the surface of the sample was saturated with such a solution. 6 There are a few reports describing high-energy radiation-induced, ionic graft polymerization.7,8 Evidence for an ionic mechanism is generally the successful grafting of a monomeric species, such as a vinyl ether, that is not prone to radical-initiated polymerization.…”

A new technique is reported for surface modification of polymers that is based upon photoinitiated cationic polymerization. The bulk, host sample is doped with a small amount of a cationic photoinitiator and exposed to radiation, thus creating a catalytic surface that, when exposed to an appropriate monomer, serves to initiate polymerization, thereby altering the surface properties of the bulk sample. The polymerization process is characterized by highly nonlinear growth kinetics. The effect of reaction variables on these kinetics has been explored and a molecular level model for the process is proposed.
