“…[26][27][28] Recently, photocatalysis process of the polymer-TiO 2 composites has been widely applied in various areas ranging from renewable energy to cleanup environment fields. [29][30][31][32][33] In the process of photocatalysis, TiO 2 nanoparticles can generate electron-hole pairs under ultraviolet (UV) light, which would produce active radical species with the photocatalytic capacity of polymer matrix. [29][30][31][32][33] The polymer chain around TiO 2 nanoparticles would be cleaved with CO 2 evolution, which thus could results in the appearance of nanopores.…”

Organic electrochemical metallization (ECM) memory that possesses high reliable switching performance is in great demand for the future smart wearable and flexible electronics. The resistive switching (RS) behavior of organic ECM memory is determined by the micro‐morphology evolution of metal conductive filaments (CFs) during the operating process. However, the morphology controllability of CFs is generally deteriorated by their random distribution and unexpected overgrowth. Herein, a kind of nanoporous PVC/TiO2 nanocomposite is developed using photocatalytic method for improving the RS reliability of organic ECM memory. The introduction of engineered nanopores can effectively simplify the CFs morphology to obtain excellent uniformity, good retention, and low cycling degradation. In addition, taking advantage of the multilevel RS behavior and 200 × 200 memristive array artificial neural network (ANN), alphabetic data storage and image pattern recognition are successfully realized. The proposed approach is expected to provide novel platforms for the advance of highly reliable flexible electronics and ANN for intelligence applications.

“…[152,[154][155][156] For example, Zhu and coworkers reported that copper phthalocyanine (CuPc) modifications enhanced the charge separation efficiency of TiO 2 , which resulted in a threefold higher photodegradation efficiency of PE than unmodified TiO 2 . [115] Apart from CuPc, nanographite, [144] polyaniline, [157,158] and polyacrylamide [118] were also reported to improve the photocatalytic performance of TiO 2 by promoting the separation of photogenerated charge carriers. In addition to TiO 2 , other photocatalysts such as ZnO, [126] ZrO 2 , [122] BiVO 4 , [159][160][161] and BiOCl [162,163] were also reported for plastics photodegradation, with some of them performing even better than TiO 2 in certain specific cases.…”

Plastic waste remains a global challenge due to the massive amounts being produced without satisfactory treatment technologies for recycling and upcycling. Photocatalytic processes are emerging as green and promising approaches to upcycle plastics into value‐added products under mild conditions using sunlight as the energy source. In this review, the recent advances in plastic conversion through photocatalysis have been comprehensively summarized. Special emphasis is placed on the photocatalytic mechanism and the selective CC and CH bond transformations of plastics to access fuels, chemicals, and materials. Finally, the challenges and the perspectives on establishing a new paradigm toward a sustainable and circular plastic economy are also put forward.

“…The results showed that the interaction of the two components in the polymer reduced the photodegradability. Najaf et al [ 50 ] used polyaniline modified TiO 2 as a photocatalyst and then combined it with polyvinyl chloride to make photodegradable films. The results showed that the quality of polyaniline decreased by 67% when the molar ratio of polyaniline to TiO 2 was 10:1 under the condition of 30W UV lamp irradiation for 720 h, decreased by 12% compared with the pure polyvinyl chloride (PVC) film, and its photodegradation performance was greatly improved.…”

In today’s world, the problem of “white pollution” is becoming more and more serious, and many countries have paid special attention to this problem, and it has become one of the most important tasks to reduce polymer waste and to protect the environment. Due to the degradability, safety, economy and practicality of biodegradable packaging film materials, biodegradable packaging film materials have become a major trend in the packaging industry to replace traditional packaging film materials, provided that the packaging performance requirements are met. This paper reviews the degradation mechanisms and performance characteristics of biodegradable packaging film materials, such as photodegradation, hydrodegradation, thermo-oxidative degradation and biodegradation, focuses on the research progress of the modification of biodegradable packaging film materials, and summarizes some challenges and bottlenecks of current biodegradable packaging film materials.
