Special Issue Information

Dear Colleagues, 

Over the years, research on polymers have significanlty increased, providing new insights into their applications for improving existing technologies and systems. A wide array of polymerization techniques are available which can polymerize most monomers, thereby leading to the formation of block copolymers (BCPs) that possess various advanced properties such as self-healing, self-assembly, high biocompatibility, and responsiveness. 

Numerous studies have already been published on the potential applications and advantages of BCPs which have substantial scientific, societal, as well as economic impacts. Nevertheless, many challenges in their development and utilization remain to be tackled, such as issues related to the synthetic procedure, scale-up, using biocompatible materials, and high technological applications. 

This Special Issue, ‘Advances and Applications of Block Copolymers II’ invites submissions of review articles, original research manuscripts, and short communications that undercore the recent progess achieved in developing and using BCPs. The keywords presented below indicate some potential topics of interest; however, the list is not exhaustive, and papers addressing any other relevant aspects of BCPs will be accepted as well.

We conducted a computational study on the self-assembly behavior of cylinder-forming block copolymers, directed by a guide pattern of hexagonally or tetragonally arrayed pillars, using mesoscale density functional theory simulations. By adjusting the spacing (Lp) and diameter (D) of the pillars in relation to the intrinsic cylinder-to-cylinder distance (L2) of the cylinder-forming block copolymer, we investigated the efficiency of multiple-replicating cylinders, generated by the block copolymer, through the pillar-directed self-assembly process. The simulations demonstrated that at specific values of normalized parameters L˜2=L2/Lp and D˜=D/Lp coupled with suitable surface fields, triple and quadruple replications are achievable with a hexagonally arrayed pillar pattern, while only double replication is attainable with a tetragonally arrayed pillar pattern. This work, offering an extensive structure map encompassing a wide range of possible parameter spaces, including L˜2 and D˜, serves as a valuable guide for designing the contact hole patterning essential in nanoelectronics applications.

Polyethylene (PE)-based elastomers are the ideal choice for enhancing the compatibility of polypropylene/polyethylene (PP/PE) blends and improving the mechanical properties of PP-based materials. However, the issue of blend systems lies in the interplay between the crystallization processes. Therefore, we investigated the crystallization behavior during the cooling process of a new generation of PP/PE block copolymers (PP-b-PE) and random polypropylene (PPR, a copolymer of propylene and a small amount of ethylene or an alpha-olefin) blends using in-situ X-ray diffraction/scattering and differential scanning calorimetry (DSC) techniques. We also conducted mechanical performance tests on PPR/PP-b-PE blends at room temperature and low temperature (−5 °C). The results indicate that during the cooling process, the PP phase of PP-b-PE will follow the PPR to crystallize in advance and form a eutectic mixture, thereby enhancing the compatibility of PP/PE. Moreover, the PPR/PP-b-PE blend will form stable β-(300) crystals with excellent mechanical properties. Due to the improved compatibility of PP/PE with PP-b-PE, PE crystals are dispersed within PP crystals, providing bonding that improves the toughness of PPR under the low stiffness failure conditions of PPR/PP-b-PE blends, thereby enhancing their impact performance at low and room temperatures. This research has great significance for both recycling waste plastics and enhancing the low-temperature toughness of PPR. Full article
