Ultraviolet (UV) ageing is one main environmental factor affecting the service performance
and life of plant fiber reinforced composites. Plant fiber treatment or modification is an …

Photo-oxidatative degradation of isotactic polypropylene (PP) has been examined in
samples made by injection and compression moulding and using different moulding …

Photochemically degradable polymers and plastics are reviewed with an emphasis on the
environmental and molecular factors that control the onset of degradation and the rate of …

An investigation has been conducted into the effects of photodegradation on the crystallinity
and melting behaviour of isotactic polypropylene (PP). PP samples having different …

Polymers are vastly employed for numerous purposes in different industrial segments and
generate soaring quantities of discarding in the environment. This research analyzed the …

The weathering behaviour of poly (ethylene terephthalate) was investigated. Samples
produced by bi-axial extrusion were exposed in the laboratory for periods of up to∼ 1100 h …

Isotactic polypropylene bars were exposed to ultraviolet radiation (UV) in the laboratory for
periods up to 48 weeks causing a reduction in molecular size and the build-up of chemical …

This review examines the mechanistic origins of the effects of stress on the photochemical
degradation rates of polymers. Recent studies have shown that tensile and shear stresses …

Abstract Microplastics (MPs) and chromium (Cr) are common pollutants in wastewater
treatment plants, where ultraviolet disinfection processes may degrade MPs and …

The impact of climatic ageing on the characteristics of both unexposed and exposed faces of
unstabilized and stabilized LDPE films was investigated. The effects on chemical and …
