We previously discovered that covalently coating glass and plastic slides with certain long poly(vinyl-N-alkylpyridinium) chains enables the resultant surfaces to kill a variety of airborne and waterborne bacteria on contact. In the present study, these findings have been extended to an unrelated polymer class, polyethylenimines (PEIs). Alkylated PEIs attached to flat macroscopic surfaces and t...

There is increasing pressure to use coatings in a more sustainable way in our society and museums and archives are not exempt from this. Coatings, including those presumed to be “green” products, have been examined in terms of their suitability for collection preservation. To be more sustainable, museums should both avoid applying a coating as much as possible. When the need is essential, then ...

There is a great concern about the indoor microbial colonization especially in places that should have high standards of environmental hygiene. Besides, due it shortened useful life coating by discoloration and degradation. Currently this problem must be solved an innovative eco-friendly way. In sense, aim work was to develop green waterborne paint formulated with microcapsules containing essen...

A waterborne ultraviolet (UV)-curing coating was prepared on the surface of wood materials with modification of talcum powder and calcium carbonate (CaCO3). When the waterborne UV-curing coatings on the surface of wood materials (WUVCW) was radiated for 1 min by UV (λ = 365 nm) and dried at 40 ◦C for 10 min, it showed good hardness, adhesion, and impact strength, with controlling the talcum con...

Fluorescent and flame-retardant two-component waterborne polyurethane coatings were synthesized using 1,5-dihydroxy naphthalene, a halogen-free polyphosphate and a hydrophilic curing agent, and their properties were systematically characterized. The average particle sizes and zeta potential values were below 170 nm and −30 mV. Meanwhile, the multifunctional two-component waterborne polyurethane...

Microcapsules of melamine formaldehyde-coated shellac and waterborne coating were prepared by in situ polymerization at 400, 600, 800 1000 rpm. The microcapsules four different stirring rates added into the primer a concentration 5.0%, 10.0%, 15.0%, 20.0% 25.0%. effects paint film on optical, mechanical liquid resistance properties investigated. results showed that comprehensive performance Til...

This thesis considers a nanotechnology approach based on the production of metals pre-treatments and organic coatings (a complete protection system at all) designed from the nanoscale. The final aim is to develop protection systems with improved corrosion protection properties and a low environmental impact. In particular, multifunctional silane hybrid molecules were used to design sol-gel pre-...
