Upcycling of Plastic Waste An optimal approach for the upcycling plastics is reported by Weipu Zhu and co-workers in article number 2210758, which permits direct manufacture high-value advanced materials avoids monomer regeneration. More specifically, a novel strategy provided directly poly(ethylene terephthalate) waste to antibacterial products. This procedure, employs catalytic amount an mono...

nanocomposites made of carbon nanotube (cnt) bundles have attracted researchers’ attention due to their unusual properties such as: light weight, flexibility and stiffness.  in this paper, the effects of straight and rope-shaped bundles on nanocomposite effective mechanical properties are investigated.  first, fea models are created consisting of cnts with different shapes of straight and rope-...

The method of formation of the composite polymer ‘diode-like’ membranes, that possess asymmetry of conductivity in electrolyte solution – a rectification effect similar to that of a p-n junction in semiconductors, is described. To prepare the ‘diodelike’ membranes, a thin polymer layer synthesized in plasma was deposited on the one side of a poly(ethylene terephthalate) track membrane. Study of...

The attachment of a marine Pseudomonas sp. to a variety of surfaces was investigated, and the number of bacteria which became attached was related to the surface charge and degree of hydrophobicity of the substratum. Large numbers of bacteria attached to hydrophobic plastics with little or no surface charge [Teflon, polyethylene, polystyrene, poly(ethylene terephthalate)]; moderate numbers atta...

Azoisobutylnitrile (AIBN) initiator was used in the treatment of most widely used domestic plastics in lieu of catalysts. The pyrolysis of low-density polyethylene (LDPE), high-density polyethylene (HDPE), polypropylene (PP), poly-ethylene terephthalate (PET) and polystyrene (PS) plastics with azoisobutylnitrile was carried out individually under nitrogen atmosphere. A series of single (plastic...

The thermomechanical and dynamic mechanical properties of films and fibres in vapour laden atmospheres and simulated dye baths were investigated in order to understand their processing behaviour. Acetone and water vapour acted as plasticisers for cellulose acetate film. 2-phenoxyethanol was found to penetrate poly(ethylene terephthalate) film above its glass transition temperature and consequen...

Having established commercial applications of hot compacted products based on polypropylene we are now actively exploring other polymers to ascertain whether these can provide practical alternatives and in particular improvements in terms of certain physical properties. We have selected polyethylene (PE), poly (ethylene terephthalate) (PET) and nylon for comparative trials. For these materials,...

The alkaline depolymerization reaction of poly(ethylene terephthalate) (PET) under quasi-solvent-free conditions was investigated. This is a new approach for recycling PET waste to its monomer building blocks: terephthalic acid and ethylene glycol. influence base particle size, temperature, rotational speed the employed laboratory kneader on yield in quasi-solid-solid depolymerized almost quant...

The C 1s X-ray absorption spectra (XAS) of poly(diallyl phthalate), poly(diallyl isophthalate), and poly(ethylene terephthalate) (PET) have been recorded using transmission detection. The phthalate segments of these polymers are isomers with different patterns of substitution (ortho, meta, para) of the methyl carboxylate groups on the phenyl ring. The C 1s and O 1s electron energy loss spectra ...
