“…Swelling equilibrium measurement were used to investigate gel content of 70/30/0.75 and 70/30/1.5 samples. Hexafluoroisopropanol is a good solvent for PGA, PCL, and MEP. , The blends were immersed in hexafluoroisopropanol for 72 h. However, all blends were completely dissolved in the solvent, indicating that the system was not cross-linked. This is probably because the reactivity of terminal hydroxyl groups with the epoxy groups is very weak.…”

Polyglycolic acid (PGA) with outstanding biodegradability and gas barrier is promising in the packaging field. Unfortunately, the poor toughness limits its application. Biodegradable and flexible polycaprolactone (PCL) was used to improve the toughness, and multifunctional epoxy polymers (MEPs) were selected as reactive compatibilizers. The spreading coefficient model indicated that MEP would be encapsulated by the dispersed phase of PCL in PGA/PCL/ MEP blends. Terminal carboxyl/hydroxyl groups of both PCL and PGA can in situ react with MEP, and the compatibility between PGA and PCL was improved greatly. The dimension of PCL domains decreased to 0.9 μm with 0.75 wt % of MEP. The fracture toughness of PGA/PCL increased by 370%, while the tensile strength increased to 49.6 MPa. When the total content of MEP was more than 0.75 wt %, excess MEP would migrate to the PGA matrix, resulting in an increase in the viscosity of the PGA matrix and a morphology evolution of PGA/ PCL blends from "sea-island" to the "co-continuous-like" structure. Therefore, this work will provide a facile method to prepare toughened sustainable green PGA-based materials with balanced strength.

“…Table 1 displays the different contributions of the total solubility parameters for the tested solvents and the polymers given by Hansen [2]. Although the proposed values for solvents are the objects of a relatively large consensus, the HSP components proposed by Hansen for polymers do meet a so general agreement [12], [14], [15], [29]. 2), (3) Relative energy distance of all the considered solvent (s)/polymer pairs for PS, PLA and PMMA.…”

Hansen solubility parameter theory and rheological laws were employed to investigate the microscopic cross‐linked network structure of the wear‐resistant elastomer based on ethylene propylene diene monomers (EPDM)‐polyamide elastomers (PAE)/graphite. With the condition of the same carbon black content, the wear volume of EPDM‐PAE increased after added wax powder and decreased by adding five percent graphite. The role of microscopic cross‐linked network on the wear‐resistant properties was specifically characterized by a highly linear synergistic relationship between wear volume and cross‐link density. The motion ability of micro chain segments has been characterized by the frequency sweep and the influence of the filler network has been represented by the strain sweep. Scanning electron microscope was used to characterize the micro filling structure, while stereomicroscope view was used to explore the wear interface. It was noteworthy that the graphite network layer formed on the abrasive surface on top of the abrasive grit wear transformed the wear mechanism into composite wear. This work was an innovative perspective to study rubber‐plastic/solid lubricant‐based wear‐resistant elastomers, based on microscopic network structures, which could help to obtain new wear‐resistant elastomers with specific properties.
