Poly(3-hydroxybutyrate) and Poly(3-hydroxybutyrate-co-3-hydroxyvalerate): Structure, Property, and Fiber
Figure 6
Mechanism for generating the planar zigzag conformation (-form) in high-strength P(3HB-co-3HV) fibers by different drawing methods: (a) cold-drawing and two-step-drawing, and (b) one-step-drawing after isothermal crystallization. The vertical arrows indicate the drawing direction [77].
