Abstract 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 accelerate the rate of the photochemical degradation of polymers. Conversely, compressive stress generally retards the rate of photochemical degradation. After an initial discussion of the photochemical auto‐oxidation mechanism, the three primary hypotheses that purport to explain how stress affects… 
On the role of chemical reactions in initiating ultraviolet laser ablation in poly(methyl methacrylate)
The role of chemical reactions is investigated versus the thermal and mechanical processes occurring in a polymer substrate during irradiation by a laser pulse and subsequent ablation. Molecular
Experimentally realized mechanochemistry distinct from force-accelerated scission of loaded bonds
Pulling on bonds counterintuitively Experimental mechanochemistry has largely focused on the application of force along chemical bonds to accelerate their cleavage. Akbulatov et al. now demonstrate
Effects of Mechanical Deformation on the Opto-Electronic Responses, Reactivity, and Performance of Conjugated Polymers: A DFT Study
The development of polymers for optoelectronic applications is an important research area; however, a deeper understanding of the effects induced by mechanical deformations on their intrinsic
Photochemical Behavior of Synthetic Polymeric Multicomponent Materials Composites and Nanocomposites
Multicomponent materials based on synthetic polymers were designed and used in a wide variety of common and hi-tech applications, including the outdoor applications as well. Therefore, their response
Surface characterization and degradation behavior of polyimide films induced by coupling irradiation treatment
The degradation behavior of polyimide in extreme environments, especially under coupling treatment, directly determines the service life of several key components in spacecraft. In this research, the
Model for photothermal ionization and molecular recombination during pulsed ablation of polyethylene
The surface erosion of polyethylene is studied under conditions characteristic of extremely high-rate heating expected in laser-driven and high energy density experiments. A coupled model for


Investigation of the origin of tensile stress-induced rate enhancements in the photochemical degradation of polymers.
Infrared and X-ray data are presented, showing that the degree of orientation and crystallinity in the polymer does indeed increase with increasing stress, consistent with a hypothesis in which stress affects the ability of the photochemically generated radicals to recombine.
Effects of Mechanical Deformation on the Photo-Degradation of Acrylic-Melamine Coatings
The effects of bending deformations on the photodegradation of cured films of the systems: n-butyl acrylate, styrene or methyl methacrylate, hydroxyethyl acrylate, and melamine coated on aluminum
Role of oxygen diffusion in polymer ageing: kinetic and mechanical aspects
For an ageing process involving the consumption of a small molecule (typically O2 or H2O) by reaction with the polymer, there are critical conditions of reaction rate and/or thickness above which the
Thermo‐oxidative and photo‐oxidative aging of polypropylene under simultaneous tensile stress
The effect of uniaxial tensile stress at constant load in the range of 0 to 6.86 MN/m2 upon the behavior of stabilized and unstabilized types of isotactic polypropylene was investigated in the course
Oxidative destruction of polymers under stress
Analysis of chain‐scission and crosslinking rates in the photo‐oxidation of polystyrene
A study of the chain-scission and crosslinking rates in polystyrene photodegraded in the laboratory with fluorescent tubes (UVA-340) was made using GPC molecular weight distributions. The analysis
