Polymer is flexible lightweight materials and can be produced into thin films at a low cost.
Furthermore, the nano ZnO/PMMA composites have potential applications in UV protecting sheets and films, transparent barrier or protective layers, antireflection coatings and as materials with increase thermal stability [11].

Common fillers in UPR formulation are flame retardant (FR) materials which used to reduce flammability of the based polymer [2].
UPR demonstrates poor fire resistance due to their high styrene content and traditional FR materials was made from halogenated ingredients which performed well until toxicity issues became important as these materials release toxic gases and corrosive smoke during fire [3].

Bicomponent Fibers for the Preparation of a New Effective Filtration Materials for Separation of Hazardous Chemicals in Technological Processes of Wood Treatment Eva RUŽINSKÁ1, a, Krzysztof J.
Due to the fact that materials prepared on the base of microfibers [11] are used as filtering with a view to the preparation of a highly efficient filtration materials for the collection of dangerous chemical substances (selected from group of VOCs) and particulate matters (dust) we were interested in evaluating the specific surface of the planar structures.
This feature can be suitably used in the application of excelent filtration materials.

NbF5 and CrF3 catalysts effects on synthesis and hydrogen storage performance of Mg-Ni-NiO composites Qi Wan, Ping Li *, Teng Wang, Xuanhui Qu Institute for Advanced Materials and Technology, University of Science and Technology, Beijing 100083, China Corresponding author: bj60106531@sina.com Keywords: Hydrogen storage; Mg-based materials; cryomilling; hydrogen storage performance; kinetics; NbF5 Abstract: Two kinds of novel materials, Mg-1.6mol%Ni-0.4mol%NiO-2mol%MF (MF=NbF5, CrF3), along with Mg-1.6mol%Ni-0.4mol%NiO for comparison, were examined for their potential use in hydrogen storage applications, having been fabricated via cryomilling.
Carbon nanotubes seem to be convenient adsorbent materials, but hydrogen storage capacity limits their potential for hydrogen storage.
It has been shown that Mg-based hydrogen storage materials, prepared with cryomilling, have excellent properties [18].
Firstly, Mg-based hydrogen storage materials fabricated by cryomilling have outstanding activation performance.
