Shape memory polymer films have been of great interests in storing functional information because their optical and mechanical variability. High molecular weight polyvinyl acetate (PVAc) is an ideal shape material to program micro- nano-scale patterns on the surface highly transparent films. By blending PVAc with polyethylene glycol (PEG) plasticizer, lower switching temperatures could be achie...

This paper presents the results of experimental and analytical studies mechanical thermal properties laterite composites mixed with reprocessed low-density polyethylene waste (LDPE), calcium phosphate (CaP) phosphogypsum wastes, biochar to form brick composites. Bricks mixtures 20% by volume LDPE, 15% CaP, gypsum were shown have excellent compressive strength, flexural fracture toughness. The 1...

There are large deposits of waste materials from various industrial or building activity all over the world. Out this enormous quantity waste, a little amount gets recycled, while rest is dumped in vulnerable places. This paper examines potential use subbase, including recycled chips derived polyethylene terephthalate plastics and cement kiln dust resulting Portland industry as by-product. Samp...

Low density Polyethylene (designated hereafter as “PE”) is known for its inactivity, durability and resistance to degradation. For this reason adding pro-oxidants additives in PE matrix could be efficient elaborate a material designated Ox-PE, exhibiting chemical reactivity. This modification lead an enhancement of compatibility between Ox-PE other functionalized polymers. approach has been exp...

Abstract A silane coupling agent, namely γ-aminopropyltriethoxysilane (APS), was used to modify kenaf powder (KP). It then as filler in a thermoplastic elastomer (TPE) based on Recycled High Density Polyethylene/Natural Rubber Blends (rHDPE/NR). The attachment of onto KP verified by Fourier Transform Infrared Spectroscopy (FTIR), while the performance TPE assessed terms mechanical and thermal p...

The majority of waste plastics currently produced are either landfilled or incinerated. Plastics do not readily degrade and toxic elements can be leached from the landfill. Combustion of waste plastics can generate environmentally hazardous air pollutants such as dioxins/furans, as well as undesirable carbon dioxide. Consequently, cost effective ways of recycling the increasing amounts of gener...

TThis study investigated the water absorption of chitosan, collagen, and chitosan/collagen blend membranes exposed to gamma-ray irradiation. These membranes were produced via the solvent evaporation method. All membranes then underwent irradiation at 15 or 25 kGy gamma-ray doses, while membranes without irradiation were used as controls. After immersing the membranes in distilled water for up t...

Polyethersulfone (PES)-based anion exchange blend membranes were prepared from quaternized-PES (Q-PES) and N-Methyl-2-pyrrolidone (NMP) casting solutions with water as coagulant via non-solvent induced phase inversion. The compatibility of the blend system was investigated through thermodynamic studies while membrane formation was determined using the cloud point techni...

Information on the preparation and properties of starch/gelatin blend microparticles with and without crosslinking for drug delivery is presented. The blend microparticles were prepared by the water-in-oil emulsion solvent diffusion method. Glutaraldehyde and methylene blue were used as the crosslinker and the water-soluble drug model, respectively. The blend microparticles were characterized b...
