“…However, the homopolymer properties of acrylate and methacrylate make it difficult to meet the requirements needed for coating film-forming materials; for example, polymethyl methacrylate, which is the raw material of plexiglass, is too brittle as a film-forming material, and polybutyl acrylate is too soft and sticky, and is not suitable for coatings. Therefore, as the film-forming material of the paint, acrylate copolymers are ideal, and are usually obtained by polymerizing different monomers [ 32 , 33 , 34 ].…”

Traditional methods that are used to deal with radioactive surface contamination, which are time-consuming and expensive. As one effective measure of radioactive material purification, strippable coating, which effectively coats the pollutant, and settles them on the surface of objects. However, there are some shortcomings in terms of film formation and peelability, such as a brittle coating and poor peelability. Therefore, in order to meet the treatment methods for radioactive contaminants needs, the strippable coating must have excellent sealing, corrosion resistance, weather resistance, low environmental pollution, short film formation time, and good mechanical properties; in addition, the spraying process should be simple, with moderate adhesion, and it should be capable of being quickly and completely peeled off. In this paper, a ternary system was prepared by pre-emulsion polymerization with butyl-acrylate, methyl methacrylate, acrylic acid as the reactive monomer, sodium dodecyl sulfate as the active agent, potassium persulfate as the initiator, and water as the dispersion medium. The Fourier-transform infrared (FTIR) spectroscopy, nuclear magnetic resonance (1H-NMR), ICP emission spectrometer, surface tension tester, and universal testing machine were used to characterize the structure and morphology of the composite materials. The results show that the decontaminant can quickly wet the powder particles and the surface pollutants. The sealing efficiency of Fe and Cu was over 90%. After the decontaminant was cured, it could be continuously formed on the surface of different substrates and be completely peeled off, as well as having excellent film formation and peelability.

“…Several architectures can be prepared using amphiphilic block copolymers for applications such as coatings, inks, paints, textile, agriculture, cosmetics and biomaterials. [1][2][3][4][5] The physical and chemical properties of amphiphilic copolymers, for example, the modulus 3 and surface tension, 6 can be adjusted by varying the block length, composition and architecture of the copolymer. These properties affect the morphology and critical micelle concentration (CMC).…”

A series of amphiphilic poly(2-hydroxyethyl methacrylate)-b-polydimethylsiloxane-b-poly(2-hydroxyethyl methacrylate) (pHEMAb-PDMS-b-pHEMA) (A-B-A) triblock copolymers were synthesized with varying block molecular weights. Control over the polymerization, micellar size and size distribution, dynamic mechanical properties, and film morphology of nine triblock copolymers was investigated as a function of block length. The polymerization resulted in copolymers with polydispersity index below 1.5. The self-assembly behavior of the triblock copolymers was studied in selective solvents for A and B blocks. The micellar diameter was determined by dynamic light scattering and transmission electron microscopy. The film morphologies were investigated by small angle X-ray scattering. Phase separation was observed when the blocks had similar molecular weights (symmetry). However, the ordering of the morphology was disrupted when the blocks lengths were asymmetric. Phase separation was observed by atomic force microscopy when the block molecular weights were symmetric. The viscoelastic properties were examined using dynamic mechanical analysis. The modulus and crosslink density increased with increasing pHEMA content.

“…However, extractives can bleed through some wood coatings, leaving a "tannin" stain on the coating surface (Burke et al 2010). Several additives and primers have been developed to address this problem (Kimerling and Bhatia 2004). Primary methods include metal-based pigments, modified functional groups, and amphiphilic block copolymers (Hart 2011).…”

Under certain conditions involving uneven exposure to weather, stains related to the extractives can reduce the aesthetic appeal of western red cedar in exterior applications such as fence boards, siding, and sidewall shingles. Selected chemical treatments were evaluated for their ability to inhibit the formation of extractives stain. DDACarbonate, alkyl amine oxide, and combinations thereof delayed extractives stain formation in an accelerated field test, with higher loadings having greater effect.
