“…The incorporation of proteins in the waterborne NPs formulation puts latex technology at a higher level, offering the possibility to improve its structural, functional, and biodegradability features. In that sense, hybrid protein-based latexes have been used to produce and study final products, including coatings, ,,,,, adhesives, ,, and films, ,, which have shown improved properties in comparison with the synthetic polymer latexes (without protein). Moreover, properties comparable to existent commercial products were obtained in some cases. ,, …”

“…These features were in most cases the result of a prepolymerization stage of protein modification, which pursues introducing extra active sites onto the protein backbone to promote its grafting with the synthetic polymer , or to modify its hydrophilic–hydrophobic balance. ,, In this scenario, highly compatibilized hybrid materials showed superior properties than the simple constituents’ addition, demonstrating a synergetic contribution of both components due to the intimate contact between phases. Some of these synergetic improvements observed in the applications of protein-based hybrid NPs were partial biodegradability, ,,,,, thermal stability, film formation with low requirement of formulation agents (better NPs coalescence), , solvent resistance, water resistance, ,,,, and mechanical strength ,,, among others.…”

“…The EF-EP proposed by Li et al, 79 previously addressed, was also employed to produce collagen/PMMA hybrid NPs. Following this strategy, Luque et al 131 recently reported the synthesis of hybrid collagen/acrylic NPs by EF-EP of AA and BA with varied HC content (from 15 to 50%) and H 2 O 2 as hydroperoxide initiator. Despite the amount of collagen incorporated being significant, with this method just a small fraction could be grafted, with a GP of approximately 10%.…”

“…The obtained latexes presented excellent film formation capability, giving place to materials with different mechanical and adhesive properties, depending on the percentage of collagen, neutralization degree, and moisture content. 131 This characteristic opens the opportunity to obtain switchable biobased materials, where the adhesion is controlled by their moisture content.…”

The pursuit of sustainable and environmentally friendly materials has been powered by environmental concerns and the decline in oil reserves. Among the different routes toward this end, the replacement of oil-based materials by renewable materials stands out. In this way, protein based materials have gained interest. This review article summarizes the progress achieved in the synthesis of hybrid protein/synthetic polymer nanoparticles which have the potential to be used in industrial applications. Although technical achievements and efficacy proofs concerning the increased compatibility of polymer/protein are already available, practical implementation in industry still represents an additional challenge and should be the focus of interest in future research. The available literature supports the potential of hybrid protein/polymer nanoparticles in the production of ecofriendly alternatives for large scale applications as coatings, paints, adhesives and films.

“…In addition, collagen has a high glass transition temperature and the polymer chains should not be moveable at room temperature. [44,45] The stability of the particles on the surface of the nanofibers is also important for long-term culture and in vivo implantation. To this end, in situ monitoring of the size and even morphology of the particles will be required before this system is applied to a longterm application that lasts for up to 1 month.…”

A simple method based upon masked electrospray is reported for directly generating both unidirectional and bidirectional density gradients of biomacromolecular particles on uniaxially aligned nanofibers. The method has been successfully applied to different types of biomacromolecules, including collagen and a mixture of collagen and fibronectin or laminin, to suit different types of applications. Collagen particles in a unidirectional or bidirectional gradient are able to promote the linear migration of bone marrow stem cells or NIH-3T3 fibroblasts along the direction of increasing particle density. In the case of particles made of a mixture of collagen and fibronectin, their deposition in a bidirectional gradient promotes the migration of Schwann cells from two opposite sides toward the center, matching the scenario in peripheral nerve repair. As for a mixture of collagen and laminin, the particles in a unidirectional gradient promote the extension of neurites from embryonic chick dorsal root ganglion in the direction of increasing particle density. Taken together, the scaffolds featuring a combination of uniaxially aligned nanofibers and biomacromolecular particles in density gradient can be applied to a range of biological studies and biomedical applications.

Latex films with high heat resistance tend to have higher Tg and the emulsion minimum film formation temperature (MFFT) is higher. Higher MFFT latexes do not produce continuous coherent films at low temperatures during application. Consequently, in order to solve the paradoxical problem of obtaining latex films with high Tg at low emulsion MFFT, a series of alkali soluble resin (ASR) stabilized latexes were synthesized in this study using a semi‐continuous pre‐emulsification polymerization process. The microstructure of latex particles, polymerization stability, composition and properties of latex films were characterized and tested by ATR‐FTIR, TEM, ZETA potential analyzer, DSC, orthomorphic metallographic microscope, and gloss tester. The results show that the addition of ASR reduces the content of coagulum during polymerization and significantly increases the number of latex particles. The high Tg ASR also induces the formation of a microphase separation structure with a dual glass transition in the latex film, which improves heat resistance. Additionally, hydroplasticized ASR reduces emulsion MFFT, improves latex film flatness, and enhances its glossiness. The introduction of ASR acts as a dual role of synergy with conventional ionic surfactants during synthesis to increase the stability of composite latexes and with polyacrylate (PA) in application to enhance its properties.
