The consistent rise of plastic pollution has stimulated interest in the development biodegradable plastics. However, study polymer biodegradation historically been limited to a small number polymers due costly and slow standard methods for measuring degradation, slowing new material innovation. High-throughput synthesis high-throughput method are developed applied generate dataset 642 chemically distinct polyesters polycarbonates. assay was based on clear-zone technique, using automation...
The fracture of polymer networks is tied to the molecular behavior strands within network, yet specific molecular-level processes that determine mechanical limits a network remain elusive. Here, question reactivity-guided explored in otherwise indistinguishable end-linked by tuning relative composition with two different mechanochemical reactivities. Increasing substitution less mechanochemically reactive ("strong") into comprising more ("weak") has negligible impact on energy until strong...
Gelation has long been conceptualized and modeled as a percolation process in which bond formation or destruction events are random. Percolation assumes that connections created destroyed randomly such the critical point should occur at same when approached from either direction. Here, gel of an end-linked poly(ethylene glycol) was measured during forward (bond forming) reverse breaking) gelation degelation processes to interrogate how scales with synthesis concentration, where decreased...
