Scanning electron microscope (SEM) samples were prepared from the vertical midline of a single non-woven mat of electrospun polyethylene oxide. Thirteen analysts with identical training and instructions measured the diameters of the nanofibers from the six SEM images and statistical analyses were performed on the resulting data. The fiber diameters were significantly different in the lower region than the upper and center regions. Furthermore, the fiber diameters in the lower region—from micrographs taken only millimeters apart—were statistically different demonstrating a statistically significant regional variation in the sample. Furthermore, statistically significant variation between the analysts also was observed, with the average fiber diameter ranging from 166 nm to 276 nm.}, journal={POLYMER TESTING}, author={Narayanan, Ganesh and Tekbudak, Merve Yasemin and Caydamli, Yavuz and Dong, Ju and Krause, Wendy E.}, year={2017}, month={Aug}, pages={240–248} }

Their glass transition temperatures were determined using DSC and were essentially unaffected by crystallinity. The glass transition temperatures of the polyesters increase linearly with the ratio of ester groups per methylene group. Extrapolations of the ratio to zero ester group content gave a reliable value for the Tg of amorphous polyethylene (PE). The experimental Tgs manifest a steeper slope on the Tg vs. ester group content plot compared to those calculated using Van Krevelen's group contribution method. The intramolecular equilibrium flexibilities were evaluated through the calculation of conformational entropies of individual polymer chains approximated by considering solely the short-range interactions between neighboring groups, as embodied in their RIS conformational models. Their calculated conformational entropies, Sconf, decrease linearly with increasing ester group content, leading to the observation that Sconf ∝ 1/Tg.}, journal={POLYMER}, author={Shen, Jialong and Caydamli, Yavuz and Gurarslan, Alper and Li, Shanshan and Tonelli, Alan E.}, year={2017}, month={Aug}, pages={235–245} }

Melting and crystallization behaviors, mechanical properties, and the birefringence of undrawn and cold-drawn fibers were investigated. Undrawn coalesced PCL fibers were observed to have 500-600% higher moduli than undrawn as-received (asr) PCL fibers and a modulus comparable to drawn asr PCL fibers. Drawn coalesced PCL fibers have the highest crystallinity, orientation, and 65% higher moduli than drawn asr PCL fibers. Drawn coalesced PCL fibers have only a 5% higher crystallinity than drawn asr PCL fibers, yet they have 65% higher moduli and lower elongation at break values. Clearly, the intrinsic alignment of the coalesced polymers is the reason for their higher moduli and lower elongation, as confirmed by the birefringence observed in drawn coalesced and asr-PCL fibers. The improved mechanical properties of coalesced PCL fibers make them a better candidate for use in tissue engineering as scaffolds.}, number={3}, journal={BIOMACROMOLECULES}, author={Gurarslan, Alper and Caydamli, Yavuz and Shen, Jialong and Tse, Shiaomeng and Yetukuri, Mahijeeth and Tonelli, Alan E.}, year={2015}, month={Mar}, pages={890–893} }

[ACS Macro Lett. 2013, 2, 770−774] described the syntheses of acrylic tetrapolymers with controlled molecular weights and tetramonomer compositions. Relative reactivity ratios of all monomer pairs were determined and used in the Walling–Briggs terminal copolymerization model along with Skeist’s equations to address the expected compositional drift in the monomer feed ratios. The anticipated control of monomer incorporation based on this approach was verified experimentally on several tetrapolyacrylates synthesized by RAFT polymerization, which additionally controlled their molecular weights. Their “new and simple paradigm combining both predictive models provides complementary synthetic and predictive tools for designing macromolecular chemical architectures with hierarchical control over spatially dependent structure–property relationships for complex applications” is extended here to the derivation of expected monad compositions, and diad, triad, and tetrad monomer sequence distributions. These were obtained directly from the comonomer reactivity ratios determined experimentally by Ting et al. Our motivation was twofold: (i) The similar chemical structures of the four acrylate monomers they selected (methyl, 2-carboxyethyl, 2-hydroxypropyl, and 2-propylacetyl acrylate) render the experimental determination of sequence distributions in the resulting tetrapolyacrylates problematic. (ii) Because they are spatially dependent structural parameters, the sequence distributions of monomer diads, triads, tetrads, etc., in co-, tri-, tetrapolymers, etc., are generally expected to correlate more closely with their properties than their overall compositions.}, number={1}, journal={MACROMOLECULES}, author={Caydamli, Yavuz and Ding, Yi and Joijode, Abhay and Li, Shanshan and Shen, Jialong and Zhu, Jiadeng and Tonelli, Alan E.}, year={2015}, month={Jan}, pages={58–63} }
