Brominated butyl rubber (BIIR) is a derivative of butyl rubber, with the advantage of high physical strength, good vibration damping performance, low permeability, aging resistance, weather resistance, etc. However, it is hard to avoid BIIR fiber sticking together due to serious swelling or merging, resulting in few studies on BIIR electrospinning. In this work, brominated butyl rubber membrane (mat) with BIIR microfiber has been prepared by electrospinning. The spinnability of elastomer BIIR has been explored. The factors influencing the morphology of BIIR microfiber membranes have been studied, including solvent, electrospinning parameters, concentration, and the rheological property of electrospinning solution. The optimal parameters for electrospinning BIIR have been obtained. A BIIR membrane with the ideal microfiber morphology has been obtained, which can be peeled from aluminum foil on a collector easily without being broken. Anti-bacterial property, the electrical conductivity of these membranes, and the mechanical properties of these samples were studied. The optimized BIIR electrospinning solution is Bingham fluid. The results of these experiments show that a BIIR membrane can be used in the field of medical prevention, wearable electronics, electronic skin, and in other fields that require antibacterial functional polymer materials.

Terrestrial bioinspired robots emulate the locomotion strategies of land animals and have potential applications in disaster response, planetary exploration, and inspection of complex terrain. This review examines the biological basis of six representative locomotion modes: multi-legged walking and running, elastic jumping, ground-coupled gliding, interface-mediated climbing, peristaltic crawling, and adaptive morphogenesis. It introduces dimensionless descriptors of their kinematics, with explicit reference scales for periodic motion and one-off events. We use morphology-function correspondence to compare representative multi-legged, quadrupedal, jumping, gliding, climbing/peristaltic, and multimodal robots with respect to mechanisms, actuation, sensing, control, quantitative performance, and application scenarios. The cited demonstrations range from laboratory mechanisms to selected quadrupedal field applications; their heterogeneous validation records do not support class-wide numerical readiness ratings. Incomplete reporting of sensing and endurance also limits comparison. The review identifies task-specific co-design needs, with sensing architectures matched to the contact and transition variables that must be regulated in each locomotion mode.
