Summary: This study reports the preparation of a tailor-made copolymer of FMA and TFEMA via RAFT polymerization, followed by modification of the furfuryl groups through DA reaction using different POSS-M contents to yield hydrophobic fluorinated copolymers with improved surface hydrophobicity and self-healing ability. The modified DA fluoropolymers showed a significant increase in water contact angle from approximately 101 degrees to 135 degrees, making them promising materials for specialty paints and coatings.

Summary: This research aims to understand the effect of adding random perfluorinated polystyrene copolymers on enhancing the hydrophobic properties of a PS matrix. The results show that the contact angle of PS/POISE-a blends increases with the additive content, mainly due to the chemical heterogeneities and the formation of crystalline fluorine-rich nodules.

Summary: Polyhedral oligomeric silsesquioxane (POSS)-containing fluorinated poly(styrene-acrylate)/SiO2 (POSS-FPSA/SiO2) composite materials were prepared by preemulsification and direct blending method. The SiO2 particles were induced aggregated onto the surface of POSS, leading to a raspberry-like structure. XPS spectra showed two different types of Si-O bonds on the surface of the composite films, with one related to Si-O groups of SiO2 and the other attributed to Si-O-Si groups obtained from sol-gel processes. Additionally, increasing SiO2 content promoted sol-gel reactions and improved thermal stability of the composite films.

Summary: Stimuli-responsive polymer films were successfully fabricated using a novel polypseudorotaxane with competitive guest-responsiveness, resulting in ordered honeycomb porous films and sphere films via breath figure method in water or ethanol atmosphere. The nanostructures of the films were influenced by solvent, concentration, and the equivalent ratio of DEP5A to PCL-b-PEG-b-PCL. The films exhibited hydrophobicity and could be manipulated to form cuboid-crystal films with varying water contact angles using a competitive guest-containing solution.

Summary: Combining reprocessing and self-healing in one material can lead to the development of sustainable materials with improved mechanical properties. We developed fluorinated acrylic-based covalent adaptable networks (CANs) that can self-heal and be reprocessed. These materials exhibit high stress at break and storage modulus and can fully recover their mechanical properties through compression molding. They also self-heal under ambient conditions.

Summary: This study demonstrates the morphology transition of amphiphilic block copolymer honeycomb-structured films from primary to hierarchical adsorption-type microporous domains. The characteristic parameters of these hierarchical films can be controlled by changing the length of segments or swelling conditions. The research also shows that amphiphilic BCP with low volume content of hydrophilic blocks can efficiently stabilize water droplets during the morphology transition. This BCP film has potential applications in wastewater treatment, novel optical devices, and size-selective separation.

Summary: This paper proposes a gradient neural network (GNN) to solve the repetitive motion generation scheme of the omnidirectional four-wheel mobile manipulator. The current solution is analyzed and found to have position errors associated with joint errors. To address this issue, an orthogonal projection repetitive motion generation (OPRMG) method is proposed, and a corresponding GNN model is established using the gradient descent method. Simulation results demonstrate the advantages of the OPRMG scheme.

Summary: A new method for removing styrene gas in nitrogen atmospheres was developed by using styrene as a proxy for VOCs. The effect of parameters such as ferrous ion concentration, hydrogen peroxide concentration, and pH values was explored on the styrene removal efficiency. Quantization of by-products was done using a TOC analyzer. The optimal process conditions resulted in an average styrene removal efficiency of 96.23% and a neural network model was constructed for predicting styrene gas residuals.
