Description
Technical Field
The invention belongs to the technical field of flexible photoelectric materials, and particularly relates to a polymer-based flexible film with an oriented bridging structure, and preparation and application thereof.
Background
The flexible photoelectric detector has wide application prospect in the fields of human health monitoring, portable optical devices, man-machine interaction, wearable visual sensing and the like. The commercial photoelectric detector mainly adopts a silicon photodiode, however, the inherent rigidity and fragility of the silicon material can not enable devices constructed by the silicon material to be well attached to human limbs, so that the accuracy of data is reduced, and the position of the wearable device on the body is limited. At present, the main strategy for preparing the flexible photoelectric detector is to transfer the photoelectric device to a flexible substrate with a special geometric structure (such as wave, snake shape and spring), but the method has the defects of complex process, poor structural reliability, insufficient deformation stability and the like.
The photoelectric semiconductor nano material is blended and filled into the polymer, and the performance of the photoelectric semiconductor material is further overlapped on the basis of keeping the intrinsic characteristics of the polymer, so that the method is a universal method for preparing the durable and stable flexible photoelectric detector. For example, zhang Ye blended black phosphorus with a polymer produced a flexible photodetector (adv. Funct. Mater. 2019, 29, 1906610) with a responsivity of 4.593 μ A W −1 The detection rate is 7.45 multiplied by 10 8 Jones; a stretchable photodetector (adv. Funct. Mater. 2021, 31, 2100136) was prepared by mixing graphene into a polyionic liquid with a responsivity of 6.19 mA W −1 The detection rate was 0.33X10 9 Jones. However, in the reported system, two-dimensional semiconductor materials such as graphene, black phosphorus and the like are dispersed in a polymer in an unordered way, so that a transition energy barrier of carriers among semiconductor material domains is large, carrier mobility is low, and photoelectric performance is poor. Therefore, there is an urgent need to develop a high-performance flexible photodetector.

Analysis of experimental results
As can be observed from the cross-section SEM of fig. 2, the one-dimensional tellurium nanowires and the two-dimensional molybdenum disulfide nanosheets are in a 'brick-mud' -shaped alternate ordered arrangement structure in the polyvinyl alcohol matrix, and the one-dimensional tellurium nanowires with high length-diameter ratio are used as connecting bridges between the molybdenum disulfide nanosheets, so that the high-speed and ordered carrier transportation is facilitated.
As can be seen from the I-V curve of fig. 3, the one-dimensional tellurium nanowire/two-dimensional molybdenum disulfide/polyvinyl alcohol flexible photodetector with an oriented bridging structure gradually increases with increasing optical power under the illumination of wavelength 532 nm.
From the I-t curve of fig. 4, it can be found that the photo-response time of the one-dimensional tellurium nanowire/two-dimensional molybdenum disulfide/polyvinyl alcohol flexible photodetector with an oriented bridge structure is 0.78s.
As can be seen from the carrier mobility diagram in fig. 5, the carrier mobility of the one-dimensional tellurium nanowire/two-dimensional molybdenum disulfide/polyvinyl alcohol flexible photodetector with the oriented bridging structure is improved by about 6 times compared with that of the one-dimensional tellurium nanowire/two-dimensional molybdenum disulfide/polyvinyl alcohol flexible photodetector with unordered distribution, and one of the beneficial effects of the oriented bridging structure in the invention is proved to be that the carrier mobility is obviously improved.
As can be seen from FIG. 6, the response and detection rate of the one-dimensional tellurium nanowire/two-dimensional molybdenum disulfide/polyvinyl alcohol flexible photodetector with the oriented bridge structure are respectively 11.32 mA/W and 1.12×1010Jones, while the response time, response and detection rate of the one-dimensional tellurium nanowire/two-dimensional molybdenum disulfide/polyvinyl alcohol flexible photodetector with unordered distribution are respectively 3.32 s, 0.356 mA/W and 0.848×10 9 Jones, the photoelectric detector prepared by the invention has obvious performance advantages.
As can be seen from fig. 7, the one-dimensional tellurium nanowire/two-dimensional molybdenum disulfide/polyvinyl alcohol flexible photodetector with the oriented bridge structure can still maintain stable photodetection performance after 30 ° and 120 ° bending.
It will be readily appreciated by those skilled in the art that the foregoing description is merely a preferred embodiment of the invention and is not intended to limit the invention, but any modifications, equivalents, improvements or alternatives falling within the spirit and principles of the invention are intended to be included within the scope of the invention.
