About this collection
Polymer Chemistry is proud to present this 2020 Emerging Investigators collection. This collection gathers the very best work from polymer scientists in the early stages of their independent careers. The 2020 Polymer Chemistry Emerging Investigators were individually nominated by members of the journal Editorial and Advisory Boards, and previous Emerging Investigators, in recognition of their potential to influence future directions in the field.
Accompanying this collection is the Emerging Investigators special issue, in which these articles will be formally published. This issue is scheduled for publication in early 2020.
