The development of polyamide fibers with excellent mechanical performance is always a hot research topic. In this paper, the structure evolution of polyamide 1212 (PA1212) after stretching at different temperatures was characterized by Wide-Angle X-ray Diffraction (WAXD) and Small-Angle X-ray Scattering (SAXS) techniques. Experimentally, it was found that there existed a maximum tensile strength of...
Hydrophilic porous polymer scaffolds have shown great application in drug controlled release, while their mechanical properties and release efficiency still need further improvement. In the current study, the porous scaffolds of polyvinyl alcohol (PVA) prepared by quenching in liquid nitrogen and freeze drying method from different original concentration aqueous solutions were fabricated. Among different...
