Welding immiscible polyethylene and isotactic polypropylene
Polyethylene (PE) and isotactic polypropylene (iPP) account for nearly two-thirds of the world’s plastic—adding up to $200 billion in annual sales worldwide. When melted together, PE and iPP are immiscible and form a brittle material. So they tend to get recycled into lower-value products because of the expense associated with sorting them from one another. Now, researchers led by Cornell University’s Geoffrey W. Coates, Anne M.
