“…air), leaving an amorphous porous material whose morphology reflects the shape and size of the original micellar system. Also, as the shape of block copolymer micelles can be modified by addition of coresoluble homopolymers to micellar solutions [26][27][28][29], the addition of PS homopolymer to the organic/inorganic sol-gel mixture was investigated. Once homopolymer molecules are incorporated into the micellar system they swell micelles affecting their size, number and shape.…”

“…To date, there are many reports on the study of the features of distributions of NPs in different polymer matrices using various approaches, such as Monte Carlo simulation [42][43][44] self-consistent field theory [45][46][47][48][49][50][51][52] and (MD) method. [35,[53][54][55] These works show that, for an adequate understanding of the structure formation in such systems, it is necessary to adopt sufficiently large lengths and time scales (>50 nm and >100 ns).…”

Mixtures of conjugated polymers (CPs) as donors and inorganic semiconducting nanoparticles (NPs) as acceptors are considered to be promising materials for photoactive layers of bulk heterojunction hybrid solar cells (HSCs). To reach the high power conversion efficiency of HSC, the morphology of the photoactive layer for providing optimal charge transport paths is designed. Herein, the coarse‐grained model for predicting the morphology of nanocomposites based on semiconducting CPs and NPs is used. For polymer matrix, well‐known CPs such as poly(3‐hexythiophene) (P3HT), poly [thieno [3,4‐b] thiophene/benzodithiophen] (PTB7), and poly [[2,6′‐4,8‐ di(5‐ethylhexylthienyl)benzo[1,2‐b;3,3‐b] dithiophene][3‐fluoro‐ 2[(2‐ethylhexyl) carbonyl] thieno[3,4‐b]thiophenediyl]] (PTB7‐Th) are selected. For NP fillers, PbS quantum dots modified by ligands (like, e.g., oleic acid) are selected. Via mesoscale computer simulations, it is shown that by choosing appropriate ligands for NPs and varying the weight fraction of NPs, the morphology with bicontinuous charge transport paths for holes and electrons is obtained. Such morphologies are observed in models of homopolymer/NP blends for the first time. This finding is in reasonable agreement with the recent experimental results on these systems.

The pH-triggered polymers are a sub-class of stimuli-responsive macromolecules. These smart polymers can experience physical or chemical transition due to small pH responses. pH-dependent materials gain great demand within a short period, by considering their potential applications. pH-triggered macromolecules typically possess weak basic or weak acidic functional groups. The functional groups often used include tertiary amines, pyridines, phosphate, and carboxylic acids. These stimuli-dependent materials are ideal candidates for the biomedical field. Herein, report pH-dependent chiral amphiphilic carbodiimide polymers. Helical polycarbodiimides consist of alternating imine and amine backbone, attached to different pendant groups. Substituting the pendant groups, enable to change of the properties of polycarbodiimides. Thus, we invented polar functional groups such as dimethylamine and piperazine to the side chains to enhance the solubility in an aqueous medium. Moreover, each unit of these polymers consists of hydrophobic methyl functionality and hydrophilic dimethyl and piperazine side groups. Thus, these carbodiimide polymers were self-assembled in aqueous solutions as well as buffer solutions due to the hydrophilic and hydrophobic moieties of the polymer. The micelles can be used as nanocarriers. Furthermore, the pH-dependent swelling properties were observed in these polymeric nanoparticles in different time intervals. Thus, the pH-triggered volume change of the micelles can be used as a controlled release, targeted site drug delivery applications.
