Special Issue Information

Dear Colleagues,

Self-assembly is a spontaneous process through which disordered components get together to form ordered structures in a multi-component material. This process is derived by the local interaction within the system and the ordered structures show collective properties that are different from those exhibited by the individual components. Polymers, due to versatility in their chemical and physical structures, offer a large number of degrees of freedom for programing the local interactions and engineering materials with optimized properties. Therefore, polymers are abundantly used in many technological and biomedical applications as a crucial class of materials that exhibit or mediate self-assembly behavior.

The purpose of this Special Issue on self-assembly in polymer melts and blends is to prepare a collection of scientific investigations that address different aspects of this behavior in polymer systems. Submissions are welcome based on any computational, theoretical and experimental approach to the fundamental understanding of the molecular origin of self-assembly and/or engineering self-assembled structures in polymer systems designed for specific applications. Manuscripts can be either original research or reviews.

Manuscript Submission Information

Manuscripts should be submitted online at www.mdpi.com by registering and logging in to this website. Once you are registered, click here to go to the submission form. Manuscripts can be submitted until the deadline. All submissions that pass pre-check are peer-reviewed. Accepted papers will be published continuously in the journal (as soon as accepted) and will be listed together on the special issue website. Research articles, review articles as well as short communications are invited. For planned papers, a title and short abstract (about 100 words) can be sent to the Editorial Office for announcement on this website.

Submitted manuscripts should not have been published previously, nor be under consideration for publication elsewhere (except conference proceedings papers). All manuscripts are thoroughly refereed through a single-blind peer-review process. A guide for authors and other relevant information for submission of manuscripts is available on the Instructions for Authors page. Polymers is an international peer-reviewed open access semimonthly journal published by MDPI.

Please visit the Instructions for Authors page before submitting a manuscript. The Article Processing Charge (APC) for publication in this open access journal is 2700 CHF (Swiss Francs). Submitted papers should be well formatted and use good English. Authors may use MDPI's English editing service prior to publication or during author revisions.

The bond fluctuation model was employed to characterize the approach to the mesophase separation transition of pure linear AB copolymers and symmetric miktoarms, also called Janus, star polymers, Af/2Bf/2 , where f = 6 or 12 is the total number of arms, in a common good solvent. We consider a concentration sufficiently high to mimic the melting behavior and also a lower concentration. The segregation between A and B units is represented by a repulsive interaction parameter, . Different total numbers of units are also considered. Results for different properties, such as the molecular size, the asphericity and orientational correlation of blocks, or arms, of different compositions are obtained as a function of the segregation parameter. We also calculate scattering structure factors. The initial effect of segregation on the scattering with opposite contrast factors between the A and B blocks can be explained with a common description based on the random phase approximation for both the linear copolymers and the f = 6 miktoarms, once the numerical form factors of the different molecules in their particular systems are considered. However, the results for f = 12 clearly deviate from this description probably due to some degree of ordering in the position of highly armed molecules. Full article
