Deformation of Unoriented Semicrystalline Polymers

At room temperature (i.e., above Tg for many semicrystalline polymers), semicrystalline polymers are tough and show large plastic deformation before fracture. A typical morphology (at the highest level) found in semicrystalline polymers is spherulite, which influences the deformation behavior of polymers. 

As seen above, the problem in dealing with semicrystalline polymers is the difficulty in controlling the morphology (varying one when others are fixed). One promising approach has been reported more recently, as explained next.
