Abstract Understanding the direct effects of hydrogen bonding (H‐bonding) on the mechanical response of glassy state polymers remains a challenge, largely owing to the use of semicrystalline polymers in such studies, wherein, separating the contrib

The fracture behavior of polyrotaxane (PR)-modified poly(methyl methacrylate) (PMMA) was investigated. PR is a supramolecule with rings threaded onto a linear backbone chain, which is capped by bulky end groups to prevent the rings from de-threading.

In polymer nanocomposites (PNCs), the physical and chemical interactions at the polymer matrix–filler interface lead to local variations in polymer properties over a substantial “interphase” region in the vicinity of the interface. Characteriza

Additive Manufacturing. 41:101964
Fused filament fabrication (FFF) is a common additive manufacturing method for polymers that has been widely adopted due to its low cost and ease of use. However, FFF remains limited in high performance applications due to the weak mechanical propert

Unlike the nominally brittle behavior of bulk polystyrene (PS), PS nanofibers with particular combinations of molecular weight (MW) and submicron scale diameters exhibit stable necking followed by pronounced strain-hardening, resulting in simultaneou

Recent advances in materials synthesis have resulted in the development of continuous carbon fibers with one micron diameter and tensile strengths exceeding 5 GPa. Mechanical experiments on such strong fibers with very small diameters require tensile

Bulk polystyrene (PS) undergoes craze-assisted brittle failure at room temperature. In this work it is shown that the synergistic coupling of the material length scale as defined by macromolecular size, and the specimen size as defined by the nanofib

Engineering complex tissues such as the tendon-to-bone insertion sites require a strong and tough biomimetic material system that incorporates both mineralized and unmineralized tissues with different strengths and stiffnesses. However, increasing st
