We demonstrate the use of combined thermal annealing and solvent vapor annealing (SVA) to tune the morphology of thermally responsive block copolymer (BCP) thin films. The BCP, poly(styrene-b-tert-butyl acrylate) (PS-b-PtBA), undergoes a chemical dep

Solvent vapor annealing (SVA) with solvent mixtures is a promising approach for controlling block copolymer thin film self-assembly. In this work, we present the design and fabrication of a solvent-resistant microfluidic mixing device to produce disc

The effects of surface functionality and relative humidity (RH) on nanomechanical contact stiffness were investigated using atomic force acoustic microscopy (AFAM), a contact scanned-probe microscopy (SPM) technique. Self-assembled monolayers (SAMs)

We present a new method for measuring the modulus of soft polymer networks (E < 10 MPa). This metrology utilizes compression-induced buckling of a sensor film applied to the surface of the specimen, where the periodic buckling wavelength, assessed ra

Block copolymer (BC) brush gradient libraries were examined as high-throughput platforms to study the effect of relative block lengths on the response to solvents. BC brushes of poly(n-butyl methacrylate) (PBMA) and poly(2-(N,N‘-dimethylamino)ethyl

We outline a method to fabricate gradient combinatorial libraries that explore architectural parameters of surface-grafted block copolymers (BCs). In addition, we demonstrate the utility of such libraries for the rapid, thorough assessment of the res

Physicochemical properties of PBLG (poly(gamma-benzyl-l-glutamate))-PEO (poly(ethylene oxide)) diblock copolymers composed of PBLG as the hydrophobic rod component and PEO as the hydrophilic component were investigated at the air-water interface. Sur

We report on the thin film phase behavior of poly(styrene)-block-poly(2-vinylpyridine)-block-poly(tert-butyl methacrylate) triblock terpolymers with volume fractions φPS:φP2VP:φPtBMA scaling as 1:1.2:x, with x ranging from 3.05 to 4. On controlled

Laboratory research informatics systems (LRIS) hold great promise in streamlining research generally, and are absolutely necessary for new data-intensive research strategies such as combinatorial and high-throughput (C&HT) approaches. In this paper,
