Study of green modification of nano-Al2O3 and enhanced scratch resistance of water-based polyacrylate varnishes
In order to enhance the physical properties of water-based polyacrylate varnishes, a green-modified water-based nano-Al2O3 dispersion was successfully prepared by regulating the content of anti-sedimentation dispersant under the condition of ultrasonication. The results prove that the prepared water-based nano-Al2O3 dispersion is obtained under the condition of 0.4 wt% anti-sedimentation dispersant and 0.5 h ultrasonic time and storage stability is observed more than 3 months. After adding water-based nano-Al2O3 dispersion at 0.5 wt% mass fraction to water-based polyacrylate varnishes bought from Carpoly, the scratch load is increased from 900 to 1500 g. The analysis of scratch surface appearance also reveals that the damage of water-based polyacrylate/Al2O3 nanocomposites film is minimal.
Graphical abstract
An easy green non-covalent surface modification of commercial nano-Al2O3 was carried out by using anti-sedimentation dispersant (alkylol ammonium salt of acidic polymer) and ultrasonication technology simultaneously, resulting in the formation of a highly well-stable dispersion reported firstly in water and good scratch resistance for water-based polyacrylate varnishes.
期刊介绍：
The objective of the Journal of Nanoparticle Research is to disseminate knowledge of the physical, chemical and biological phenomena and processes in structures that have at least one lengthscale ranging from molecular to approximately 100 nm (or submicron in some situations), and exhibit improved and novel properties that are a direct result of their small size.
Nanoparticle research is a key component of nanoscience, nanoengineering and nanotechnology.
The focus of the Journal is on the specific concepts, properties, phenomena, and processes related to particles, tubes, layers, macromolecules, clusters and other finite structures of the nanoscale size range. Synthesis, assembly, transport, reactivity, and stability of such structures are considered. Development of in-situ and ex-situ instrumentation for characterization of nanoparticles and their interfaces should be based on new principles for probing properties and phenomena not well understood at the nanometer scale. Modeling and simulation may include atom-based quantum mechanics; molecular dynamics; single-particle, multi-body and continuum based models; fractals; other methods suitable for modeling particle synthesis, assembling and interaction processes. Realization and application of systems, structures and devices with novel functions obtained via precursor nanoparticles is emphasized. Approaches may include gas-, liquid-, solid-, and vacuum-based processes, size reduction, chemical- and bio-self assembly. Contributions include utilization of nanoparticle systems for enhancing a phenomenon or process and particle assembling into hierarchical structures, as well as formulation and the administration of drugs. Synergistic approaches originating from different disciplines and technologies, and interaction between the research providers and users in this field, are encouraged.
