“…Hurell and Cameron , separated the degradation process into four stages: water diffusion, insertion crystallization, molecular weight reduction, and erosion through the diffusion of degraded small molecules and the homogenization of degradation throughout the sample. Matsuno et al studied the degradation behavior of PGA fiber by immersing the samples in phosphate-buffered saline at various temperatures. The results show that when the segmental motion of PGA in the fiber mats was released, the apparent crystallinity of the mats increased, meaning that PGA amorphous chains were cleaved and thus partially eluted into the aqueous phase.…”

With the wide application of the PGA material, its service life has become a major concern. Present study was aimed to investigate the hydrolysis mechanisms of poly(glycolic acid) (PGA) via characterization of micromolecular structure and macroproperties. The goal was to establish a foundation for controlling and predicting the service life of the PGA in the future. The results showed that degradation was initiated by cleavage of the ester bonds with the formation of acid products through Fourier transform infrared spectroscopy (FT-IR). The hydrolysis products were identified as glycolic acid, glycolic acid dimer, and its oligomer through chromatography (GPC), high-performance liquid chromatography (HPLC), and liquid chromatograph mass spectrometer (LC-MS). According to the principle of time–temperature superposition, it was found that the degradation activation energy was 58 kJ/mol after processing the mechanical properties of degraded PGA. This work provides significant guidance for modifying PGA and its future appliances.

Poly(glycolic acid) (PGA) is a rapidly degradable polymer mainly used in medical applications, attributed to its relatively high cost. Reducing its price will boost its utilization in a wider range of application fields, such as gas barriers and shale gas extraction. This article presents a strategy that utilizes recycled PGA as a raw material alongside typical carbon nanomaterials, such as graphene oxide nanosheets (GO) and carbon nanotubes (CNTs), to produce low-cost, fully degradable yarns via electrospinning and twisting techniques. The results demonstrate that the tensile strength of the PGA/GO composite yarn increased to 21.36 MPa, and the elastic modulus attained a value of 259.51 MPa with a 3 wt% of GO loading. The addition of an appropriate amount of GO enhances the tensile resistance of the composite yarns to a certain extent. However, excessive application of GO and CNTs can lead to surface defects in the nanofibers, reducing their mechanical properties. Moreover, the integration of both materials could inhibit the degradation process of PGA to some extent, thereby partially addressing the issue of excessive degradation rates associated with the relatively low molecular weight of recycled PGA.
