A copolymer with lamellar morphology
Journal of Research of the National Bureau of Standards Section A: Physics and Chemistry, 1964 Electron microscopy, together with wide- and small-angle x-ray diffraction studies, indicates that copolymers of tetrafluorocthylene and hexafluoropropylene are lamellar. The lamellar development is extensive; the lamellae can be broad and extend for many microns. The perfluoromethyl groups are incorporated within the lamellae as point defects.

Machine Learning‐Enabled Polymer Discovery for Enhanced Pulmonary siRNA Delivery
Advanced Functional Materials, EarlyView.This study provides an efficient approach to train a machine learning model by merging heterogeneous literature data to predict suitable polymers for siRNA delivery. Without the need for extensive laboratory synthesis, the machine learning enabled a virtual screening and successfully predicted a polymer that is validated for effective gene silencing in

Kinetics and thermodynamics of first-order Markov chain copolymerization
, 2014 We report a theoretical study of stochastic processes modeling the growth of first-order Markov copolymers, as well as the reversed reaction of depolymerization. These processes are ruled by kinetic equations describing both the attachment and detachment

Decoding the Structure of Benzodithiophene Polymers for High‐Efficiency Organic Solar Cells
Advanced Functional Materials, EarlyView.This study reveals a unique solid mesophase in top‐performing benzodithiophene‐based polymers for solar cells, comprising stacked solid‐like and liquid‐like layers. Combining nanoscale fibrillar domains with amorphous regions, it introduces a new structural paradigm.
