Abstract: Micron-sized surface cracks develop in polybutadiene when stretched and exposed to ozone. The consequent reduction in the transparency of the rubber provides a method for quantifying the ambient ozone concentration. The rate at which opacity develops depends linearly on the amount of ozone, and increases with increasing strain. This method of detecting atmospheric ozone has high sensitivity (1 ppb) and a broad dynamic range. The crack morphology can be interpreted in terms of nucleation and growth.

Fig. 4. Ozone cracking ‘master curve’ obtained by superposition of the data in Fig. 3. Error bars have been omitted for clarity. The inset shows the factors by which the abscissa values were shifted in order to generate the master curve. 
Fig. 5. Comparison of light transmission at two different strains. The open circles are measurements for samples stretched 76%, while the broken lines are from the master curve in Fig. 4. The decrease in strain increased the response time by a factor of 2.3.

TL;DR: Gent et al. as mentioned in this paper described the molecular basis of rubber-like elasticity and showed that the strength of elastomers can be improved by reinforcement of Elastomers by Particulate Fillers.

The Attack of Ozone on Stretched Rubber Vulcanizates. I. The Rate of Cut Growth
M. Braden,A. N. Gent +1 more
TL;DR: In this paper, the propagation of a cut through a stretched rubber sheet under the action of an atmosphere containing ozone was studied and a well-defined rate of cut growth was determined which is characteristic of growth through the bulk and substantially independent of the applied tensile stress when this exceeds a critical value necessary for growth to occur at all.

Ozone Crack Depth Analysis for Rubber
TL;DR: In this paper, a method has been developed which follows the change in crack depth as the criterion of the extent of damage that has taken place, and it has been shown that, when crack growth takes place, the depth increases proportionally.

Role of ozone in dynamic cut growth of rubber
G. J. Lake,P. B. Lindley +1 more
TL;DR: In this paper, the effect of ozone on the growth of cuts in rubber strips subjected to repeated tensile deformations has been investigated, and it was shown that ozone is not responsible for all the cut growth, and in this region the rate of growth is substantially independent of tearing energy.
