Nanocomposite Poly(lactic acid)/sepiolite with Improved Mechanical and Biofilms Formation Properties
Nanocomposites of poly(lactic acid) with sepiolite needles (5 wt.%) were evaluated in terms the mechanical and biofilm formation properties. The nanocomposite exhibited higher values Young�s modulus tensile strength at break compared to PLA, without detriment percent elongation break. These improvements related high aspect ratio nanoclay, polymer-clay interactions, degree dispersion. growth Pse...
Polyamide-66(PA66)/CaCO3 micro- and nano-composites were prepared using a polymer solution method at filler loading of 0, 1, 2 and 3 weight percent. Nano-size of CaCO3 was synthesized by micro-emulsion technique. The material was characterized by XRD, SEM, FTIR and UV-VIS techniques. XRD results of composites suggested that CaCO3 particles are found in the amorphous phase of the semi-crystallin...
In this paper, the implications of melt compatibility on thermal and solid-state properties of linear low density polyethylene/high density polyethylene (LLDPE/HDPE) blends were assessed with respect to the effect of composition distribution (CD) and branch content (BC). The effect of CD was studied by melt blending a metallocene (m-LLDPE) and a Ziegler-Natta (ZN) LLDPE with the same HDPE at 19...
We have investigated multiple ionization of N(2) and O(2) molecules by 52 nm extreme-ultraviolet light pulses at the free-electron laser facility SCSS in Japan. Coulomb break-up of parent ions with charge states up to 5+ is found by the ion-ion coincidence technique. The charge-state dependence of kinetic energy release distributions suggests that the electrons are emitted sequentially in compe...
The effect of silicone nano-emulsion softener against silicone conventional emulsion softener on the physical properties of cotton fabric has been studied. It is observed that the nano-emulsion softener improves the feel, softness and crease recovery to a higher extent compared to the conventional emulsion softener. However, the nano form of emulsion causes higher loss in strength with increase...
Determining the aging state of low-voltage nuclear power plant cables using a nondestructive and reliable condition monitoring technique is highly desirable as experience multiple stresses during service period. This paper deals with implementation investigation such techniques, which can detect overall instrumentation control (I&C) cables, are subjected to accelerated thermal aging. The di...
Membranes were prepared from alkaline lignin and poly(vinyl alcohol) (PVA) by a film casting method, and their properties were evaluated. These blend membranes can aptly be termed as green by nature as they are totally non-toxic and eco-friendly. The optimal mass ratio was determined based on the mechanical properties of membranes. The microstructure, mechanical properties, oxygen and carbon di...
Edible films and coatings have currently received increasing interest because of their potential in food applications. This study examined the effect incorporated essential oils natural plant extracts on characteristics composite seaweed hydrocolloid gac pulp films. Films were prepared by a casting technique, followed measurement physical, optical, barrier, mechanical, structural properties. Th...
Transparent wood developed by impregnating poplar with epoxy resin assisted by silane coupling agent
Biodegradable transparent wood was fabricated by introducing epoxy resin E51 modified with the silane coupling agent (KH550) into bleached poplar veneer. The light transmittance of modulated KH550 content. able to change compatibility and substrate, thereby affecting performance wood. In this study, effect on properties its mechanism were investigated. transmittance, tensile strength, elongatio...
As widely distributed vast reserves of emerging green energy, solar energy has gained widespread attention in recent years. Photovoltaic (PV) power generation is one the most scientific ways to use energy. In PV systems, polyethylene terephthalate (PET) chief material backsheets. It well known that backsheets will encounter various challenges, among which partial discharge (PD) these cause dete...
